Multiply (4 + r) * (3 + 3r)
2r(4(3 + 3r) + r(3 + 3r)) = 0
2r((3 * 4 + 3r * 4) + r(3 + 3r)) = 0
2r((12 + 12r) + r(3 + 3r)) = 0
2r(12 + 12r + (3 * r + 3r * r)) = 0
2r(12 + 12r + (3r + 3r2)) = 0

Combine like terms: 12r + 3r = 15r
2r(12 + 15r + 3r2) = 0
(12 * 2r + 15r * 2r + 3r2 * 2r) = 0
(24r + 30r2 + 6r3) = 0
