Answer:
In that quadratic equation:
a = 2 b = 3 and c = 1
b^2 -4*a*c equals
9 -4 * 2 * 1 =
9 -8=
1
Explanation:
We are finding the discriminant of the function
It needs to be written in the form ax^2 +bx+c =0
2x^2 +3x = -1
Add 1 to each side
2x^2 +3x+1 = -1+1
2x^2 +3x+1 = -0
b^2 -4ac
a=2 b=3 and c = 1
3^2 - 4(2)(1)
9 - 8
