A) $2 x ^ { 2 } + 5 x - 42$
B) $x ^ { 2 } - 42 x + 5$
C) $2 x ^ { 2 } + 4 x - 42$
D) $x ^ { 2 } + 5 x + 4$

Question

Quizplus · Accepted Answer

Using the FOIL method (First, Outer, Inner, Last) for multiplying polynomials: First: $2x \cdot x = 2x^2$, Outer: $2x \cdot 6 = 12x$, Inner: $-7 \cdot x = -7x$, Last: $-7 \cdot 6 = -42$. Adding these together: $2x^2 + 12x - 7x - 42 = 2x^2 + 5x - 42$.
