(4a - 2b + 3) (a + b) - (6b - 70 + 2a) (a-c)
a(4a - 2b + 3) + b(4a - 2b + 3) - a(6b - 70 + 2a) + -c(6b - 70 + 2a)
4a² - 2ab + 3a + 4ab - 2b² + 3b - 6ab - 70a + 2a² - 6bc + 70c - 2ca
(4a² + 2a²) + (-2b²) + (-2ab + 4ab - 6ab) + (-6bc) + (-2ca) + (3a - 70a) + (3b) + (70c)
(6a²) + (-2b²) + (-4ab) + (-6bc) + (-2ca) + (-67a) + (3b) + (70c)
6a² - 2b² - 4ab - 6bc - 2ca - 67a + 3b + 70c
