simplify expression 9m^2-1/3m+3
As shown below, this factors, but that is as far as you can take it:
[(3m-1)(3m+1)]/[3(m+1)]
simplify expression 9m^2-1/3m+3
As shown below, this factors, but that is as far as you can take it:
[(3m-1)(3m+1)]/[3(m+1)]
Starting with:
[9m^2-1]/[3m+3]
factoring the denominator:
[9m^2-1]/[3(m+1)]
rewriting the numerator as:
[(3m)^2-1^2]/[3(m+1)] "difference of squares" -- special case factoring
[(3m-1)(3m+1)]/[3(m+1)]
canceling like-terms:
(3m-1)/3
or
m - 1/3
