Use the quadratic formula.

Answer 2

can you help me with that

Answer 3

Sure, so if you have the equation \[2x^2 + 3x +5=0 \] you need to complete the square. Do you know how to do that?

Answer 4

b=-+squared b^2-4ac/2a

Answer 5

Yeah. Plug all the terms into the quadratic formula.

So it would be \[x=-3\pm \sqrt{3^2-4(2)(5)}/2(2)\]

Answer 6

By the way, that means divide everything by 2(2)
