-4(7(7 + x) + -1x * (7 + x)) = 4x(x + -5)
-4((7 * 7 + x * 7) + -1x * (7 + x)) = 4x(x + -5)
-4((49 + 7x) + -1x * (7 + x)) = 4x(x + -5)
-4(49 + 7x + (7 * -1x + x * -1x)) = 4x(x + -5)
-4(49 + 7x + (-7x + -1x2)) = 4x(x + -5)

Combine like terms: 7x + -7x = 0
-4(49 + 0 + -1x2) = 4x(x + -5)
-4(49 + -1x2) = 4x(x + -5)
(49 * -4 + -1x2 * -4) = 4x(x + -5)
(-196 + 4x2) = 4x(x + -5)
