$(-4x - 1)(5x + 2)$
answer
you must answer all questions above in order to submit.

Explanation:

Step1: Split binomials into terms

First binomial: $-4x, -1$; Second binomial: $5x, 2$

Step2: Fill box with products

	$-4x$	$-1$
$2$	$(-4x)(2)=-8x$	$(-1)(2)=-2$

Step3: Combine like terms

$-20x^2 + (-5x -8x) + (-2)$

Step4: Simplify the expression

$-20x^2 -13x -2$

Answer:

$\boldsymbol{-20x^2 -13x -2}$
