x=--2 and x=1/2

Step-by-step explanation:

this is the answer in simple form

Answer 2

Answer:

x1 = -2; x2 = $\frac{1}{5}$ or 0.5

Step-by-step explanation:

$2x^{2}+3x=2$

$2x^{2} +3x-2=0$

$D=b^{2} -4ac$

$D=3^{2}-4*2*(-2)$

$D=9+16=25=5^{2}$

$x=\frac{-b+-\sqrt{D} }{2a}$

$x=\frac{-3+5}{2*2} =\frac{2}{4} =\frac{1}{2} = 0.5$

$x=\frac{-3-5}{2*2}=-\frac{8}{4} =-2$

x1 = -2; x2 = $\frac{1}{5}$ or 0.5
