Question

Find x and y intercepts y=(2x+10)(x-2)

Answer 1

Step-by-step explanation:

$y = (2x + 10)(x - 2)$

$y = 2x(x - 2) + 10(x - 2)$

$y = 2x ^{2} - 4x + 10x - 20$

$y = 2x ^{2} + 6x - 20$

$to \: find \: x \: intercept \: y = 0$

$0 = 2x ^{2} + 6x - 20$

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

$to \: find \: y \: intercept \: x = 0$

$y = 2(0)^{2} + 6(0) - 20$

$y = - 20$
