What is the value of the discriminant for the quadratic equation 0 = x + 2 + x2? discriminant = b2 – 4ac

Explanation:

Rearrange 0 = x + 2 + x^2 into x^2 + x + 2 = 0

Note that we have something in the form ax^2 + bx + c = 0

where a = 1, b = 1, c = 2

Plug these three values into the discriminant formula

d = b^2 - 4ac

d = 1^2 - 4*1*2

d = 1 - 8

d = -7

∠cbe and ∠deb are same-side interior angles.
