Worth 20 points and will mark ! an expression is shown below: 3x3y + 12xy − 9x2y − 36y part a: rewrite the expression so that the gcf is factored completely. show the steps of your work. (4 points) part b: rewrite the expression completely factored. show the steps of your work. (6 points

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
