Question

Step 1

First multiply 3 and -20. So -60.

Then we have to factor -60 so that sum of the factors =7

-60= -5 times 12

So we will write 7y=-5y+12y

Step 2

Then we factor by grouping.

Answer(a): (3y-5)(y+4)

Step 3

We have to multiply 1 and -27. So -27

Then we factor -27 so that sum of the factor...
