Quadratic Roots and Discriminant

If the Discriminate is greater than 0 it has how many roots?

• 0

• 1

• 2

• 3

If the Discriminate is equal to 0, it has how many roots?

• 0

• 1

• 2

• 3

The graphs above show the discriminates as

• greater than 0, less than 0, equal to 0

• less than 0, equal to 0, greater than 0

• less than 0, greater than 0, equal to 0

• equal to 0, less than 0, greater than 0

Using the quadratic equation, for this function f(x)=3x²+4x−8 the discriminate indicates we will have

• 2 real roots and 0 imaginary roots

• 2 imaginary roots and 0 imaginary roots

• 1 real root and 1 imaginary root

• 1 real root and 0 imaginary roots

• 1 imaginary root and 0 real roots

When the discriminant is greater than zero and is a perfect square, the quadratic has

• 1 real rational solution

• 2 real rational solutions

• 2 real square root solutions

• 2 imaginary solutions

The discriminant is 8, what kind of solutions does the quadratic have?

• real rational

• real irrational

• real rational

• imaginary

If b²-4ac is negative, the quadratic equation has:

• Two real solutions

• Two imaginary solutions

• One real solution

• No solution

If the discriminant is positive, then the solution will be

• one real solution

• two real solutions

• no real solutions

• one imaginary solution

If the graph of a quadratic does not intercept the x-axis at any point, then it has:

• 1 Real Solution
