Simplifying
3g(g + -4) + -2g(g + -7) = g(g + 6) + -28

Reorder the terms:
3g(-4 + g) + -2g(g + -7) = g(g + 6) + -28
(-4 * 3g + g * 3g) + -2g(g + -7) = g(g + 6) + -28
(-12g + 3g2) + -2g(g + -7) = g(g + 6) + -28

Reorder the terms:
-12g + 3g2 + -2g(-7 + g) = g(g + 6) + -28
-12g + 3g2 + (-7 * -2g + g * -2g) = g(g + 6) + -28
-12g + 3g2 + (14g + -2g2) = g(g + 6) + -28

Reorder the terms:
-12g + 14g + 3g2 + -2g2 = g(g + 6) + -28

Combine like terms: -12g + 14g = 2g
2g + 3g2 + -2g2 = g(g + 6) + -28

Combine like terms: 3g2 + -2g2 = 1g2
2g + 1g2 = g(g + 6) + -28

Reorder the terms:
2g + 1g2 = g(6 + g) + -28
2g + 1g2 = (6 * g + g * g) + -28
2g + 1g2 = (6g + g2) + -28

Reorder the terms:
2g + 1g2 = -28 + 6g + g2

Solving
2g + 1g2 = -28 + 6g + g2

Solving for variable 'g'.

Reorder the terms:
28 + 2g + -6g + 1g2 + -1g2 = -28 + 6g + g2 + 28 + -6g + -1g2

Combine like terms: 2g + -6g = -4g
28 + -4g + 1g2 + -1g2 = -28 + 6g + g2 + 28 + -6g + -1g2

Combine like terms: 1g2 + -1g2 = 0
28 + -4g + 0 = -28 + 6g + g2 + 28 + -6g + -1g2
28 + -4g = -28 + 6g + g2 + 28 + -6g + -1g2

Reorder the terms:
28 + -4g = -28 + 28 + 6g + -6g + g2 + -1g2

Combine like terms: -28 + 28 = 0
28 + -4g = 0 + 6g + -6g + g2 + -1g2
28 + -4g = 6g + -6g + g2 + -1g2

Combine like terms: 6g + -6g = 0
28 + -4g = 0 + g2 + -1g2
28 + -4g = g2 + -1g2

Combine like terms: g2 + -1g2 = 0
28 + -4g = 0

Factor out the Greatest Common Factor (GCF), '4'.
4(7 + -1g) = 0

Ignore the factor 4.

Subproblem 1

Set the factor '(7 + -1g)' equal to zero and attempt to solve: Simplifying 7 + -1g = 0 Solving 7 + -1g = 0 Move all terms containing g to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1g = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1g = 0 + -7 -1g = 0 + -7 Combine like terms: 0 + -7 = -7 -1g = -7 Divide each side by '-1'. g = 7 Simplifying g = 7

Solution

g = {7}
