Solving Quadratics with Intersection

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3
*remember right side should =0

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Solve Using the Quadratic Formula

x² + 4x - 40 = -8

• x = -10 and x = -4

• x = -4 and x = 10

• x = -8 and x = 4

• x = 8 and x = -4

Use the quadratic formula to solve: n² = 9n - 20

• n = 4 and n = -5

• n = -4 and n = 5

• n = -4 and n = -5

• n = 4 and n = 5

Identify the zeros of the graph

• (0, -3)

• (-1, 0) and (3, 0)

• (1, -4)

• None of the above

Solve for x: 

• x = {-4, -1}

• x = {-1, -4}

• x = {2+i, 2-i}

• x = {-2+i, -2-i}

Solve for x:

• x = {-3+2i, -3-2i}

• x = {7, 6}

• x = 2±i√3

• No solution

How many zeros does this parabola have? 

• 3

• 2

• 0

• 1

What is this?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.

What is another word for zeros?

• y-intercepts

• roots

• vertex

• axis of symmetry

Solve
a² + 2a - 24 = 0

• a = -6, 4

• a = 6, -4

• a = 12, -2

• a = 8, -3
