Question

What is the solution to 2x2+x+2=0

Answer 1

2x2 =4, so now we have 4+x+2=0. then add 4 + 2, now we have 6+x=0. move the six over the other side of the x now we have the answer x = -6

Answer 2

`2x^2 + x + 2 = 0`

`x = (1)/(8)(-1 \pm √(1- 4(2)(2)))= (-1 \pm √(-15))/(8)`

`x = (-1 \pm i√(15))/(8)`

Two solutions, complex conjugates.
