B. $\frac{-3}{4}$ ± $\frac{\sqrt{41} }{4}$

Step-by-step explanation:

First, substitute the equation into the quadratic formula.

$x=\frac{b+-\sqrt{(b^{2} )-4(a)(c)} }{2a}$

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

Solve for x.

x= $\frac{-3+-\sqrt{9+32} }{4}$

x= $\frac{-3+-\sqrt{41} }{4}$

The answer is x= $-\frac{3}{4}$ ± $\frac{\sqrt{41} }{4}$

-- "Perimeter" means the distance all the way round the shape.

-- A square has 4 sides, and they're all the same length.

-- If one side is 12 cm long, then all 4 of them are, and the distance
all the way around the square is (4 x 12) cm.
