Use FOIL in Polynomial Multiplication
-$$( 2 x - 7 ) ( 5 x - 1 )$$
A) $10 x ^ { 2 } - 37 x + 7$
B) $7 x ^ { 2 } - 37 x + 7$
C) $10 x ^ { 2 } - 37 x - 37$
D) $7 x ^ { 2 } - 37 x - 37$

Quizplus · Accepted Answer

Using FOIL (First, Outer, Inner, Last) to multiply the polynomials: First: $2x \cdot 5x = 10x^2$, Outer: $2x \cdot (-1) = -2x$, Inner: $-7 \cdot 5x = -35x$, Last: $-7 \cdot (-1) = 7$. Adding these together gives $10x^2 - 37x + 7$.
