Answer:
1
Step-by-step 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

Answer:
20
Step-by-step explanation:
20 because 1 equals 20 I know this because 80 divided by 4 equals 20 and 100 divided by 5 equals 20 I could go on down to seven but by now you get my point.
