(x + 4)(x + 2) = __________.
Answer(s): D
Multiply the first variable in the first set of parentheses with the first variable in the second set of parentheses (x × x = x2).Next, multiply the first variable in the first set of parentheses with the second number in the second set of parentheses (x × 2 = 2x). So far, the results are x2 + 2x.Now, multiply the second number in the first set of parentheses to the first variable in the second set of parentheses (4 × x = 4x).Next, multiply the second variable in the first set of parentheses to the second number in the second set of parentheses (4 × 2 = 8).The solution is x2+ 2x + 4x + 8.Combining the like terms results in x2+ 6x + 8.
