Question

Write the roots of an equation x² – 3x - 10​

Answer 1

Hey mate hope it helps you.

x² - 3x - 10 = 0

x² + 2x - 5x - 10 = 0

x(x+2) - 5(x+2) = 0

(x+2)(x-5) = 0

x = -2 or 5

Answer 2

$\huge{\underline{\sf{\red{Answer}}}}$

$\huge \implies \large \sf \: {x}^{2} - 3x - 10 \\ \huge \implies \large \sf \: {x}^{2} - 5x + 2x - 10 \\ \huge \implies \large \sf \: x(x - 5) + 2(x - 5) \\ \huge \implies \large \sf \: (x - 5)(x + 2)$
