Question

Plzzzzzzz i need this one done ssooooooon

An expression is shown below:

2x3y + 18xy − 10x2y − 90y

Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)

Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

Answer 1

Part A:

2y*3 x+2y*9x-2y*10-2y*45

sorry i am not sure for part A

Part B:

2y(2x-45y)

Explanation:

Part A:

2y*3 x+2y*9x-2y*10-2y*45

Part B:

2x3y + 18xy − 10x2y − 90y

=2y(3x+9x-10x-45y)

= 2y(2x-45y)

Answer 2

2y

Explanation:

2x3y + 18xy - 10x2y - 90y

6xy + 18xy - 20xy - 90y

All terms can be factored by y and 2.
