Solution for (x+4)*(3x-7)=(x-2)*(3x+8) equation:


Simplifying
(x + 4)(3x + -7) = (x + -2)(3x + 8)

Reorder the terms:
(4 + x)(3x + -7) = (x + -2)(3x + 8)

Reorder the terms:
(4 + x)(-7 + 3x) = (x + -2)(3x + 8)

Multiply (4 + x) * (-7 + 3x)
(4(-7 + 3x) + x(-7 + 3x)) = (x + -2)(3x + 8)
((-7 * 4 + 3x * 4) + x(-7 + 3x)) = (x + -2)(3x + 8)
((-28 + 12x) + x(-7 + 3x)) = (x + -2)(3x + 8)
(-28 + 12x + (-7 * x + 3x * x)) = (x + -2)(3x + 8)
(-28 + 12x + (-7x + 3x2)) = (x + -2)(3x + 8)

Combine like terms: 12x + -7x = 5x
(-28 + 5x + 3x2) = (x + -2)(3x + 8)

Reorder the terms:
-28 + 5x + 3x2 = (-2 + x)(3x + 8)

Reorder the terms:
-28 + 5x + 3x2 = (-2 + x)(8 + 3x)

Multiply (-2 + x) * (8 + 3x)
-28 + 5x + 3x2 = (-2(8 + 3x) + x(8 + 3x))
-28 + 5x + 3x2 = ((8 * -2 + 3x * -2) + x(8 + 3x))
-28 + 5x + 3x2 = ((-16 + -6x) + x(8 + 3x))
-28 + 5x + 3x2 = (-16 + -6x + (8 * x + 3x * x))
-28 + 5x + 3x2 = (-16 + -6x + (8x + 3x2))

Combine like terms: -6x + 8x = 2x
-28 + 5x + 3x2 = (-16 + 2x + 3x2)
