Question

x² – 3x - 10 = 0 by using zero product rule.​

Answer 1

Answer:

$x = 5 \: \: \:or - 2$

Step-by-step explanation:

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