Use Foil to solve

(2x-2)(4x-8)

Mathematical Equivalence

ON

Answer explanation

(2x-2)(4x-8)

1. 1. First - 2x times 4x = 8x²

2. 2.Outside- 2x times -8 = -16x

3. 3.Inside - -2 times 4x = -8x

4. 4. Last - -2 times -8 = 16

Combine like terms

8x²-24x+16

• 5x²+16x+8

• 6x²+12x+8

• 6x²+16x+6

• 6x²+16x+8

Multiply these binomials.

( x + 6 ) ( x - 8 )

• x² - 2x + 48

• x² - 2x - 48

• x² + 2x - 48

• x² - 48
