Question

Solve the quadratic equation, rounding to thousandths when necessary: $3 x ^ { 2 } + 2 = 50$
A)x=4,-4 
B)X=2,-2 
C)x=16,-16 
D) $x = 4 i , - 4 i$

First, subtract 2 from both sides to get $3x^2 = 48$. Then, divide by 3 to get $x^2 = 16$. Taking the square root of both sides gives $x = \pm 4$.
