236226 + 5262320320 + 6 + 25 + 0 + 65 = 5262556642
It is: 0.3+25 = 25.3
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
yes that is correct
75 - 100 + 0 = -25
The discriminant is 25.
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
The discriminant is 0.
x=-.25.
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
x = 25 / 3squared + 5
