Question

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

Answer 1

y = -20

x- 2, -5

Explanation:

Answer 2

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`
