The 'c' value of a quadratic equation is ____________.

• The coefficient of the quadratic term.

• The coefficient of the linear term

• The constant term

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

In the equation

y = x² +5x +7

match each number with its correct letter.

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

Identify the 'c' value: y = 16x² -8x -24

• 16

• -8

• 8

• -24

Identify the value of a, b, and c given the quadratic equation 3x - 5x² = 10.

• a = 3

  b = -5

  c = 10

• a = -5

  b = 3

  c = -10

• a = -3

  b = 5

  c = -10

• a = 10

  b = -3

  c = - 5

Solve for x.

x² + 3x - 4 = 0

• x = 2 and x = - 2

• x = - 4 and x = 1

• x = 4 and x = - 1

• x = -2 and x = -2

Do you need to set the equation equal to zero before starting The Quadratic Formula?

• Yes!

• Only if you want to.

• No!
