Can someone give me a step by step instruction on solving it?
First factor out the common 4:
Now turn your attention to the trinomial:
This is called the "ac" method.
Multiply the leading coefficient with the constant, in this case
Now form a list of the pairs of factors of -6:
Now compare the sum of each pair of factors with the coefficient of the linear term of the quadratic, in this case 1. I get that 3 + (-2) = 1. So we want to write the linear term of the quadratic as .
Now factor by grouping:
