What is the solution to 2x^2+x+2=0 ? ?

Let's solve your equation step-by-step.

2x^2+x+2=0

Use quadratic formula with a=2, b=1, c=2.

x = -b ± (sqrt) b^2 - 4ac / 2a

x = -(1) ± (sqrt) (1)^2 - 4(2)(2) / 2(2)

x = -1 ± (sqrt) -15 / 4

So the answer is the last one

x = 1 ± i (sqrt) 15 / 4

For me i think it'll land on blue
