Simplifying
(3x + -8)(x + 7) = 13x + -56
Reorder the terms:
(-8 + 3x)(x + 7) = 13x + -56
Reorder the terms:
(-8 + 3x)(7 + x) = 13x + -56
Multiply (-8 + 3x) * (7 + x)
(-8(7 + x) + 3x * (7 + x)) = 13x + -56
((7 * -8 + x * -8) + 3x * (7 + x)) = 13x + -56
((-56 + -8x) + 3x * (7 + x)) = 13x + -56
(-56 + -8x + (7 * 3x + x * 3x)) = 13x + -56
(-56 + -8x + (21x + 3x2)) = 13x + -56
Combine like terms: -8x + 21x = 13x
(-56 + 13x + 3x2) = 13x + -56
Reorder the terms:
-56 + 13x + 3x2 = -56 + 13x
Add '56' to each side of the equation.
-56 + 13x + 56 + 3x2 = -56 + 56 + 13x
Reorder the terms:
-56 + 56 + 13x + 3x2 = -56 + 56 + 13x
Combine like terms: -56 + 56 = 0
0 + 13x + 3x2 = -56 + 56 + 13x
13x + 3x2 = -56 + 56 + 13x
Combine like terms: -56 + 56 = 0
13x + 3x2 = 0 + 13x
13x + 3x2 = 13x
Add '-13x' to each side of the equation.
13x + -13x + 3x2 = 13x + -13x
Combine like terms: 13x + -13x = 0
0 + 3x2 = 13x + -13x
3x2 = 13x + -13x
Combine like terms: 13x + -13x = 0
3x2 = 0
