Question

(X-4) (x+2)=16
What’s the standard form

Answer 1

Explanation:

(x-4)(x+2)=16

`x^(2)`+(-4+2)x+(-4)×2=16

`x^(2)` - 2x - 8 - 16= 0

`x^(2)` -2x -24 = 0

Answer 2

Explanation:

`(x - 4)(x + 2) = 16 \\ {x}^(2) + (- 4 + 2)x + ( - 4) * 2= 16 \\ {x}^(2) - 2x - 8 - 16 = 0 \\ {x}^(2) - 2x - 24 = 0 \\ is \: the \: standard \: form.`
