The discriminant tells you how many solutions there are to an equation The discriminant is b2-4ac For example, two solutions for a equation would mean the discriminant is positive. If it had 1 solution would mean the discriminant is zero If it had no solutions would mean that the discriminant is negative

If you mean: 4x squared+7x+4 then the discriminant is -15

If the discriminant is negative, there are 0 interceptsIf the discriminant is zero, there is 1 interceptIf the discriminant is positive, there are 2 intercepts

The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.

That depends on the values of the polynomial but in general:- If the discriminant is greater than zero it has 2 solutions If the discriminant is equal to zero then it has 2 equal solutions If the discriminant is less than zero it has no solutions

The discriminant is 16

12

The discriminant is -7

The discriminant can be positive, zero or negative.

The discriminant is 88.

The discriminant is 0.

b2-4ac is the discriminant of a quadratic equation.

If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.

The discriminant is 0.

The discriminant is 49.

The discriminant is 88.

The discriminant of x^2 + 6 - 16 = discriminant of x^2 - 10 is 40.

If the discriminant of a quadratic equation is zero then it has equal roots. If the discriminant is greater than zero then there are two different roots. If the discriminant is less than zero then there are no real roots.

The discriminant is 121.

The discriminant, for what it is worth in an example such as this, is 11.

The discriminant is 0.

With the standard notation, If b2 < 4ac then the discriminant is negative If b2 = 4ac then the discriminant is zero If b2 > 4ac then the discriminant is positive

b^2 - 4ac, the discriminant will tell you that a quadratic equation may have one real solution( discriminant = 0 ) , two real solutions( discriminant > 0 ), or no real solutions( discriminant < 0 ).

If the discriminant is a perfect square, it makes calculation easy on paper. Otherwise, the only property of the discriminant that matters is whether it is positive, negative or zero.

The discriminant is -199.
