<PRE><B>Question 177639</B>
We 1st need to multiply “c” by “a,” which gives us – 9 x 20  =  - 180
Now, we need to find 2 factors that when multiplied, they give us – 180, and when added, they give us – 3 (“b”). These 2 factors are: - 15 and 12


We then use the GCF of each binomial to factor each one, starting with the 1st
5x(4x -  3) + 3(4x -   3). Make sure that the two binomials, in parentheses (4x – 3), are equal.


Therefore, the factors are:  (5x  +  3)(4x  -  3)
