Solution for a(a+4)-6(a+4)=a(a-4)+6(a-4) equation:


Simplifying
a(a + 4) + -6(a + 4) = a(a + -4) + 6(a + -4)

Reorder the terms:
a(4 + a) + -6(a + 4) = a(a + -4) + 6(a + -4)
(4 * a + a * a) + -6(a + 4) = a(a + -4) + 6(a + -4)
(4a + a2) + -6(a + 4) = a(a + -4) + 6(a + -4)

Reorder the terms:
4a + a2 + -6(4 + a) = a(a + -4) + 6(a + -4)
4a + a2 + (4 * -6 + a * -6) = a(a + -4) + 6(a + -4)
4a + a2 + (-24 + -6a) = a(a + -4) + 6(a + -4)

-24 + -2a + a2 = a(-4 + a) + 6(a + -4)
-24 + -2a + a2 = (-4 * a + a * a) + 6(a + -4)
-24 + -2a + a2 = (-4a + a2) + 6(a + -4)

Reorder the terms:
-24 + -2a + a2 = -4a + a2 + 6(-4 + a)
-24 + -2a + a2 = -4a + a2 + (-4 * 6 + a * 6)
-24 + -2a + a2 = -4a + a2 + (-24 + 6a)

Reorder the terms:
-24 + -2a + a2 = -24 + -4a + 6a + a2

Combine like terms: -4a + 6a = 2a
-24 + -2a + a2 = -24 + 2a + a2
