Which expression is equivalent to (2x² + 3)(x + 4) ?
A.) 2x³ + 12 B.) 2x² + 11x + 12 C.) 2x³ + 6x² + 4x + 12 D.) 2x³ + 8x² + 3x + 12
Use the distributive property or FOIL method, which create the same result when multiplying two binomials.
(2x² + 3)(x + 4) = 2x²(x) + 2x²(4) + 3(x) + 3(4) {used FOIL method / distributive property} = 2x³ + 8x² + 3x + 12 {multiplied through, adding exponents on same base, when multiplying} D.) 2x³ + 8x² + 3x + 12 Ask Algebra House Comments are closed.
