Question

Write an equivalent expression to 16x + 20 using factoring.

Answer 1

Answer:

4(4x + 5)

Step-by-step explanation:

4 goes into both 16 and 20.

4×4 is 16 and

4×5 is 20.

When factoring you put the nunber you factored out typically, in front. Then the remaining factor goes in a set of parenthesis.

This is like undoing distributive property.

16x + 20

= 4(4x+5)

Answer 2

• 16x+20

Take 2 common

• 2(8x+10)

Again take two common

• 2(2(4x+5)

Simplify

• 4(4x+5)

Done
