Irrational Quadratic

In a quadratic equation, what do you call the value of \(b^2-4ac\) ?

• Square Root

• Radical

• Numerator

• Discriminant

Find the DISCRIMINANT of 3x^2-6x-11=0 and then state the number and type of solutions.

• 168; Real, Unequal, Irrational

• -96; Imaginary, Unequal

• 138; Real, Unequal, Irrational

• 0; Real and Equal

Identify the roots of the quadratic.

• x = {-1, 3}

• x = {-3}

• x = {1, -4}

• x = {1}

Use completing the square to put this equation in vertex form.

b² - 16b + 58 = 6
