5 answers
2x^2 + 3x = 90
2x^2+3x=90
2x^2+3x-90=0
(2x+15 )(x-6)=0
x = -7.5 or x = 6
2x^2+3x-90=0
(2x+15 )(x-6)=0
x = -7.5 or x = 6
Okay. Ms. Sue
2x^2+3x=90
2x^2+3x-90=0
(2x+15) (x+6)=0
X=-7.5 or X=6
Therefore X=6
Since the answer can't be in negative form
2x^2+3x-90=0
(2x+15) (x+6)=0
X=-7.5 or X=6
Therefore X=6
Since the answer can't be in negative form
