(2x +1)(x + 2)
OpenStudy (amistre64):
do you know why factoring is easier to solve it with?
OpenStudy (anonymous):
So is (2x + 1) (x+ 2) = 0 2x + 1 = 0 2x = -1 / 2 = -0.5 The other x+2 = 0 x = 2 Would that be right?
OpenStudy (amistre64):
thats good, but x = -2 for the second one ... you mighta had a typo

Many Thanks amiste I just needed confirmation that I was using the right method!
