Question

x sqaure-3x-10=0 find the roots of the following quadratic equations by factorisation​

Answer 1

Step-by-step explanation:

$x {}^{2} - 3x - 10 = \\ x {}^{2} - 5x + 2x - 10 = 0 \\ x(x - 5) + 2(x - 5) = 0 \\ (x - 5)(x + 2) = 0 \\ x - 5 = 0 \\ x = 5 \\ x + 2 = 0 \\ x = -$

$x + 2 = 0 \\ x = - 2$
