Question

The roots of a quadratic equation are 5 and -2 then , the equation is​

Answer 1

Answer:

$x ^{2} - 3x - 10 = 0$

Step-by-step explanation:

5 and -2 are the roots of a quadratic equation

∴ $x = 5, x = -2$

∴ $x - 5 = 0, x + 2 = 0$

∴ $(x - 5)(x + 2) = 0$

∴ $x^{2} + 2x - 5x - 10 = 0$

∴ $x ^{2} - 3x - 10 = 0$
