Answer:

x=3,-0.5

Step-by-step explanation:

Given : 2x^2+7x+32x

To Find: x

Solution:

We will use discriminant rule  : x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

a = 2

b = 7

c= 3

Substitute the values .

x=\frac{-7\pm\sqrt{7^2-4(2)(3)}}{2(2)}

x=\frac{-7+\sqrt{7^2-4(2)(3)}}{2(2)},\frac{-7-\sqrt{7^2-4(2)(3)}}{2(2)}

x=3,-0.5x=3,−0.5
