Break the 4 terms into groups of two. Factor the GCF out of the first two terms. Factor the GCF out of the last two terms. If the parentheses for each group match, you can think of the parentheses as...
Determine the GCF .If it is 1 then continue with the next step but if it is a number such as three then remove that number and divide each monomial by that number and put the polynomial within a set...
for example x2- 16 factors out to be (x+4)(x-4) x2- 25= (x+5)(x-5) x2 - 36= (x+6)(x-6) its as easy as that, but it doesnt work if the problem is like x2 + 36... it has to be minus-thats why there are...
