BRAINLIESTTT ASAP! PLEASE HELP ME :)

Answer 1

Answer:

$\displaystyle 1\frac{1}{2}, -3 = x$

Step-by-step explanation:

2x² + 5x - 9 = 2x

- 2x - 2x

_____________

2x² + 3x - 9

$\displaystyle 2x^2 + 3x - 9 \\ \\ [2x^2 - 3x] + [6x - 9] \\ x[2x - 3] \: \: \: \: \: 3[2x - 3] \\ \\ [x + 3][2x - 3] \\ \\ 1\frac{1}{2}, -3 = x$

I am joyous to assist you anytime.

Answer 2

2xx+5x-9=2x
2xx+3x-9=0
2xx+6x-3x-9=0
2x(x+3)-3(x+3)==
(2x-3)(x+3)=0
roots: x={1.5,-3}
