Question 262782
here is the problem:
{{{8x3 - 12x2 + 6x - 9}}}
step 1 - put (_)  around first and then second pair of terms as follows:
{{{(8x^3 - 12x^2) + (6x - 9)}}}
step 2 - find the GCF of the first and second (_) 
{{{4x^2(2x-3) + 3(2x-3)}}}
step 3- find the GCF of the entire expression to get
{{{(2x-3)(4x^2+3)}}}
