Question

Standard form. (x+8)(x−6)

Answer 1

x^2-2x-48

Explanation:

FOIL

Firsts = x*x = x^2

outside = x*-6 = -6x

inside = 8*x = 8x

lasts = 8*-6 = -48

add all together x^2-6x+8x-48 = x^2-2x-48

Answer 2

x² + 2x - 48

Explanation:

( x + 8 ) ( x - 6 )

= x ( x - 6 ) + 8 ( x - 6 )

= x*x - 6*x + 8*x + 8*( - 6 )

= x² - 6x + 8x - 48

= x² + 2x - 48
