Quadratic Roots, Zeros

If a quadratic equation has roots of x = 3 and x = -2/5, what would the factors be?

What are the zeros of the quadratic function?
y = x² - 2x - 15

• x = -2
  x = -15

• x = -3
  x = 5

• x = 3
  x = -5

• x = 1
  x = -16

Find the zeros for the following

4x² + 4x + 1 = 0

• x = -½

• x = -2

• x = 0

What is another word for zeros?

• y-intercepts

• roots

• vertex

• axis of symmetry

Find the roots/zeros of x² + x - 2

• -1, 2

• -2, 1

Find the roots of this quadratic.

• b=4/5, b=3

• b=4, b=-3

• b=1/5, b=3

• b=4/5, b=-3

x²-14x-51=0

• x= 17, -3

• x= -17, 3

• x= -17, -3

True or false:
The solutions, roots, x-intercepts, and zeros of a quadratic equation 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 is one of the solutions to this equation?
(2x - 1)² = 49

• 7

• -7

• -4

• -3

What are the x- intercepts?
These are also known as the roots, zeroes and solutions!! 
These are the points where the parabola goes through the X - AXIS

• x= 0 and x= -4

• x= 0 and x= 4

• y= 0

• x= 2
