Question

An expression is shown below:

3x3y + 12xy − 9x2y − 36y

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

Explanation:

so part a :

9y + 12xy - 18y - 36y ----- simplified

3y(3 + 4x - 6 - 12) ----- factorized ( by rearranging)

part b :

-45y +12xy ---- adding, subtracting like terms

-3y(15 - 4x) ---- fully factorized

hope this helps!
