The discriminant is -199.

Discriminant = 52 - 4 x 2 x (-8) = 89

The discriminant is -7

The discriminant is 121.

-7 therefore the quadratic equation has no real roots

The discriminant is 385.

It is: 25-4(8*6) = -167

The discriminant is 9.

2X2+5x-12 4+5x-12 -8+5x 5x-8

Discriminant = (b2-4ac) = (25 - 4x2x3) = 1

It has no solutions because the discriminant of the quadratic equation is less than zero.

15,000 to the third power that equals pi plus 12 would make it the square root of 7
