Question

factorize x^2 - x - 72​

Answer 1

$\huge\bold\red{ANSWER}$

(x – 9)(x + 8)

Explanation:

x – 72 = x – 9x + 8x – 72 -

x(x – 9) + 8(x – 9) = (x – 9)(x + 8)

= (x – 9)(x + 8)

Answer 2

${x}^{2} - x - 72 = 0 \\ {x}^{2} - 9x + 8x - 72 = 0 \\ x(x - 9) + 8(x - 9) = 0 \\ (x - 9)(x + 8) = 0 \\ x - 9 = 0 \: \: \: \: \: \: x + 8 = 0 \\ x = 9 \: \: \: \: \: \: x = - 8$
