Factor out the GCF of 4 from each term in the polynomial.

Factor out the GCF of 4 from
For a polynomial of the form find two factors of (-24) that add up to b (10).In this problem (which is and (which is , so insert 4 as the right hand term of one factor and as the right-hand term of the other factor.

Remove the fraction by multiplying the first term of the factor by the denominator of the second term.
4(x+4)(3x-2)
