What is real solution of an equation?

Frequently, in Algebra class, you will be called to find all real solutions of an equation. Such questions essentially are asking you to find all solutions of an equation, and should any imaginary solutions (containing the imaginary number ‘i’) come up, to discard these solutions.

What is a real solution example?

The number of solutions is determined by the discriminant. If the discriminant is zero, then there is exactly one real solution. For example, in the quadratic equation x2 + 4x + 4 0, its discriminant is equals to. b2 u2212 4ac (4)2 u2212 4(1)(4) 0 and so the equation has exactly one real solution.

What is meant by real solution?

Real solution definition In chemistry, a real solution is a homogeneous mixture of at least two chemical substances. A real solution differs from a colloidal solution (colloid). According to the concentration of the solute, a distinction is made between hypotonic solution, saturated solution, unsaturated solution.

How do you know if an equation has real solutions?

If the discriminant is positive, there are exactly 2 real solutions. If the discriminant is zero, there is exactly one real solution (a repeated root). If the discriminant is negative, there are exactly 2 complex solutions (they are complex conjugates), with no real solution.

What are two real solutions?

It is called the Discriminant, because it can discriminate between the possible types of answer: when b2 u2212 4ac is positive, we get two Real solutions. when it is zero we get just ONE real solution (both answers are the same) when it is negative we get a pair of Complex solutions.

How do you find the real solution?

The discriminant is the expression b2 – 4ac, which is defined for any quadratic equation ax2 + bx + c 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has.

What are all real solutions?

Frequently, in Algebra class, you will be called to find all real solutions of an equation. Simplify the equation as much as possible. For instance, if given the equation x4 + x2 – 6 0, you can use a u-substitution to simplify and then factor. If x2u, then the equation becomes u2+u-60.

What is real and non real solutions?

A non-real solution is a solution to a math equation, where the equation has the root of a negative number, which cannot be found using only real numbers – which are numbers that can be defined along a single axis.

How do you know if two solutions are real?

A real solution in algebra is simply a solution to an equation that is a real number.

What qualifies as a real solution?

The number of solutions is determined by the discriminant. If the discriminant is zero, then there is exactly one real solution. For example, in the quadratic equation x2 + 4x + 4 0, its discriminant is equals to. b2 u2212 4ac (4)2 u2212 4(1)(4) 0 and so the equation has exactly one real solution.

How do you find all real solutions?

Combine like terms on both sides of the equation. Isolate the x term by subtracting x from both sides. You arrive at the true statement 3 3. When you end up with a true statement like this, it means that the solution to the equation is all real numbers.

What is a non real solution?

For example, 3 + 2i is nonreal, 2i is nonreal, but 3 is real. As we have seen, there can be 0 , 1 , or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b 2 – 4ac) , is positive, negative, or zero. This expression has a special name: the discriminant.

What are real solutions?

If the value of the discriminant is positive, there are two real solutions for x, meaning the graph of the solution has two distinct x-intercepts. If the value of the discriminant is zero, there is one real solution for x, meaning the graph of the solution has one x-intercept.
