Using the distributive property (FOIL method), we multiply each term in the first parenthesis by each term in the second parenthesis: $3x \cdot x + 3x \cdot 7 - 2 \cdot x - 2 \cdot 7 = 3x^2 + 21x - 2x - 14 = 3x^2 + 19x - 14$.

Multiply - (3x−2)(x+7)(3 x-2)(x+7)(3x−2)(x+7) A) x2−14x+19x^{2}-14 x+19x2−14x+19 B) x2+19x+18x^{2}+19 x+18x2+19x+18 C) 3x2+19x−143 x^{2}+19 x-143x2+19x−14
