Simplifying
3(2a + 1) + 4(2 + -2a) = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)

Reorder the terms:
3(1 + 2a) + 4(2 + -2a) = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)
(1 * 3 + 2a * 3) + 4(2 + -2a) = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)
(3 + 6a) + 4(2 + -2a) = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)
3 + 6a + (2 * 4 + -2a * 4) = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)
3 + 6a + (8 + -8a) = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)

Reorder the terms:
3 + 8 + 6a + -8a = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)

Combine like terms: 3 + 8 = 11
11 + 6a + -8a = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)

Combine like terms: 6a + -8a = -2a
11 + -2a = (a + -2)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)

Reorder the terms:
11 + -2a = (-2 + a)(a + 2) + -1(8a + a2) + 2a + 4(a + -1)

Reorder the terms:
11 + -2a = (-2 + a)(2 + a) + -1(8a + a2) + 2a + 4(a + -1)

Multiply (-2 + a) * (2 + a)
11 + -2a = (-2(2 + a) + a(2 + a)) + -1(8a + a2) + 2a + 4(a + -1)
11 + -2a = ((2 * -2 + a * -2) + a(2 + a)) + -1(8a + a2) + 2a + 4(a + -1)
11 + -2a = ((-4 + -2a) + a(2 + a)) + -1(8a + a2) + 2a + 4(a + -1)
11 + -2a = (-4 + -2a + (2 * a + a * a)) + -1(8a + a2) + 2a + 4(a + -1)
11 + -2a = (-4 + -2a + (2a + a2)) + -1(8a + a2) + 2a + 4(a + -1)

Combine like terms: -2a + 2a = 0
11 + -2a = (-4 + 0 + a2) + -1(8a + a2) + 2a + 4(a + -1)
11 + -2a = (-4 + a2) + -1(8a + a2) + 2a + 4(a + -1)
11 + -2a = -4 + a2 + (8a * -1 + a2 * -1) + 2a + 4(a + -1)
11 + -2a = -4 + a2 + (-8a + -1a2) + 2a + 4(a + -1)

Reorder the terms:
11 + -2a = -4 + a2 + -8a + -1a2 + 2a + 4(-1 + a)
11 + -2a = -4 + a2 + -8a + -1a2 + 2a + (-1 * 4 + a * 4)
11 + -2a = -4 + a2 + -8a + -1a2 + 2a + (-4 + 4a)

Reorder the terms:
11 + -2a = -4 + -4 + -8a + 2a + 4a + a2 + -1a2

Combine like terms: -4 + -4 = -8
11 + -2a = -8 + -8a + 2a + 4a + a2 + -1a2

Combine like terms: -8a + 2a = -6a
11 + -2a = -8 + -6a + 4a + a2 + -1a2

Combine like terms: -6a + 4a = -2a
11 + -2a = -8 + -2a + a2 + -1a2

Combine like terms: a2 + -1a2 = 0
11 + -2a = -8 + -2a + 0
11 + -2a = -8 + -2a

Add '2a' to each side of the equation.
11 + -2a + 2a = -8 + -2a + 2a

Combine like terms: -2a + 2a = 0
11 + 0 = -8 + -2a + 2a
11 = -8 + -2a + 2a

Combine like terms: -2a + 2a = 0
11 = -8 + 0
11 = -8

Solving
11 = -8
