Question 200823: Find b^2 - 4ac and the number of real solutions
-3x^2 + 7x = 0
Answer by RAY100(1637) (Show Source): You can put this solution on YOUR website!
-3x^2 +7x +0 =0
,
a= (-3),,,,,,b= (7),,,,,,,,,c=0
.
Discriminant = b^2 -4ac = (7)^2 - 4 (-3) (0) = 49
.
D > 0 ,,,,,therefore 2 real numbers as solutions,,,,,,0,,,2.3333
.
if D = 0,,,,,, one solution
.
if D less than 0 = no real solutions
