Question

(x+5)(x-2)=0 find the roots of given equation​

Answer 1

(x+5)(x-2)

x²-2x+5x-10

x²+3x-10

Answer 2

Step-by-step explanation:

$(x + 5)(x - 2) \\ \\ = x(x - 2) + 5(x - 2) \\ \\ = {x}^{2} - 2x + 5x - 10 \\ \\ = {x}^{2} + 3x - 10 = 0 \\ \\ {x}^{2} + 5x - 2x - 10 = 0 \\ \\ x(x + 5) - 2(x + 5) = 0 \\ \\ (x - 2)(x + 5) = 0 \\ \\ so \: \: roots \: are \: \: 2 \: \: and \: \: - 5$
