It is 9m^2 - 9 = (3m + 3)*(3m - 3).
4 + 3m is already in its simplest form.
8
3 meters. 9m2/3m Divide both sides by 1m 9m/3 Simplify 3m
6m + 5 = 3m - 4Subtract 3m from each side:3m + 5 = -4Subtract 5 from each side:3m = -9Divide each side by 3:m = -3
3m^2 - 9m = 0 factor out 3m 3m(m - 3) = 0 m = 0 -------- or m = 3 --------
mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)
m(3m + 2)
6(3m - 2n)(3m + 2n)
5m+3=3m+9 5m+3-3=3m+9-3 5m=3m+6 5m-3m=3m+6-3m 2m=6 (2m)/2=6/2 m=3
There is a formula for the "difference of squares." In this case, the answer is (3m + 13n)(3m - 13n)
It is 9m^2 - 9 = (3m + 3)*(3m - 3).
3m
When m = 3 the value of 3m is 3*3 = 9
(m + 5)(3m - 1)
They are equal. 1m = 100cm 3m = 300cm
4 + 3m is already in its simplest form.
