The discriminant is 25.
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
A=0 b=0 c=0
2x^2 + 8x + 3 = 0
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
yes that is correct
The discriminant is 25.
x=-.25.
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
x = 25 / 3squared + 5
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
Discriminant = (b2-4ac) = (25 - 4x2x3) = 1
Yes because if 1+0=1 than 0 plus b equals b
-25
It is: 25-4(8*6) = -167
A=0 b=0 c=0
25/4 or 6.25
