You can put this solution on YOUR website! This is the ac, arch or grouping method. If your teacher has named her method, let us know what it is and someone might know their method. There's several methods for factoring. This is in form
a=3, b=-17, and c=10
Replace b with two numbers that multiply to give you a*c, but add to give you b.
a*c=3*10=30, and b=-17
-2*-15=30 and -2-15=-17 group the 1st two terms and the 2nd two terms: Factor the GCF from each parenthesis. Factor out the (x-5)
Happy Calculating!!!
