Question

give any two examples for quadratic equation with real root​

Answer 1

Step-by-step explanation:

If a quadratic equation has two real equal roots α, we say the equation has only one real solution.

Example: Let 3x2 + x - 2 = 0 be a quadratic equation. ...

3 ∙ (-1)2 + (-1) - 2 = 0.

So, x = -1 is a root of the quadratic equation 3x2 + x - 2 = 0.

But x = 2 is not a root of 3x2 + x - 2 = 0 because 3 ∙ 22 + 2 - 2 ≠ 0.
