#1) 9x^2+6x+1=0

#2) -2x^2+3x-2+0

I will be happy to critique your work.

what is b^2-4ac?

#1) 9^2-4(6)(1)=

81-4(6)=

81-24=57

so then 57 is the solution but what is the discriminant or is 57 the discriminant?

#2) -2^2-4(3)(-2)=

4-144= -140

Then -140 would that be the solution or the discriminant?
