(15 points ) asap! also show your work! solve.
use the quadratic formula. write solutions in simplist radical form. 2x^2+2x-1=0

Step-by-step explanation:

The quadratic formula of a quadratic equation:

Discriminant of a Quadratic is

If Δ < 0, then an equation has no real solution (has two complex solutions)

If Δ = 0, then an equation has one real solution

If Δ >0, then an equation has two real solutions

==========================================

We have the equation:

Substitute:

   simplify by 2

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60
