How would I setup (5x -2) * (2x + 2) ? (Setup, not solve!)

• (5x * 2x) + (5x * 2) + (-2 * 2x) + (-2 * 2)

• (5x * -2) + (2x * 2) + (5x * -2x) + (2 * -2)

• (5x - 2 * 2x) + (-2 * 2x + 2)

• (-5x + 2) + (2x * 2) + (-2 *2x)

SOLVE (-3w + 5) * (4w - 8)

• -12w² + 44w- 40

• -12w² -4w - 40

• 12w² + 4w + 40

• -7w² -2w - 13
