Solving Quadratic Equations

Say 'TRUE' or 'FALSE'
Every Quadratic equation has exactly one root

• TRUE
• FALSE

Which value is the vertex?

• (-4, 0)

• (-1, -9)

• (0, -8)

• (2, 0)

True or false:

The solution, root, x-intercept, and zero are all the same thing.

• True

• False, because the solution and root are the same but the x-intercept and zero are different

• False, because the x-intercept and root are the same but the zero and solution are different

• False, they are all different

What are the zeroes of this graph?

• x = -4 and 2

• x= -1 and 0

• x = 9 and -8

• x= 4 and -2

What are the zeroes?

• x= 0 and x= -4

• x= 0 and x= 4

• y= 0

• x= 2 and x= -2

What is the equation of this parabola in it’s factored form?

• y=(x-2)(x+3)

• y=(x+2)(x-3)

• y=(x+2)(x-3)(x-6)

• y=(x+3)(x-6)

What is the factored quadratic equation in the following graph?

• y=(x+2)(x+6)

• y=x²-8x+12

• y=(x-2)(x-6)

• y=(x-4)(x+4)

Solve the equation by factoring.

• x = {3,8}

• x = {-3,8}

• x = {3,-8}

• x = {-3,-8}

Solve the equation by factoring.

• x = {-5,-3}

• x = {5,-3}

• x = {-5,3}

• x = {5,3}
