The discriminant is 88.

The discriminant is -7

The discriminant is 88 which means that the given quadratic equation has two different solutions for x

The discriminant is 88.

The discriminant is -199.

The discriminant is 25.

The discriminant is 1.

-7

Trinomial

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

quadratic

(-2x3 - 2x2 + 12x) = -2x (x2 + x - 6) = -2x (x + 3) (x - 2)

-7 therefore the quadratic equation has no real roots

2x2 + 10x - 3 The discriminant is defined as b2 - 4ac, so for this function b=10, a=2, and c=-3 So the discriminant is 100-4*2*-3 = 124

2x2+5x+3 = (2x+3)(x+1) when factored

The discriminant is 49.

x3 - 2x2 + x - 2 =(x - 2)(x2 + 1)

There are no solutions to this quadratic equation because the discriminant is less than zero.

A quadratic polynomial.

2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation

It cannot be factored because the discriminant of this quadratic expression is less than zero.

If it was expressed as a quadratic equation it would have no roots because the discriminant is less than zero

(x - 2)(x2 + 1)

2x2
