Answer 2

Step-by-step explanation:      

Step 1: Simplify

$(2x -8)(2x+9)$ - Equation

$= (2x+-8)(2x+9)$ - Simplify

$=(2x)(2x)+(2x)(9)+(-8)(2x)+(-8)(9)$ - Answer

$= 4x^2+18x-16x-72$ - Simplify again

$=4x^2+2x-72$ - Final Answer

Explanation in words (Short Form)

-  The first step is to use the formula and simplify it. So first we will Rewrite the division as a fraction.

- The second step is to simplify the equation that was provided. The equation is (2x-8)(2x+9). We will apply the FOIL Method (Math) to solve this equation. Here is the formula: $\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

Answer:  

$=4x^2+2x-72$
