Math II Solving Quadratics Equations

ax²+bx+c=0  is the standard form of a quadratic equation.

• True

• False

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• A.

  a = 4, b = -8, c = 3

• B.

  a = 4, b =-8, c =-3

• C.

  a = 4, b = 8, c = 3

• D.

  a = 4, b = 8, c = -3

What value of c would make this a perfect sqaure trinomial?
x² +8x + c

• A. 4

• B. 16

• C. 64

• D. - 16

• A. x = 4

• B. x = 2

• C. x = - 2

• D. x= - 4

• A. 1

• B. 3

• C. 1/3

• D. -1/3

• A.

  Divide both sides f the equation by 3.

• B.

  Take the square root of both sides of the equation.

• C.

  Subtract 12 from both sides of the equation.

• D.

  Find two values with a sum of 5 and a product of 12.

Solve using the Quadratic Formula:

2x² + 2x − 12 = 0

• x = −2, 3

• x = 2, 3

• x = 2, −3

• x = −2, −3

Solve by factoring

• -4, 2

• -2, 4

• -16

• -4

Solve by factoring. (HINT: Factor GCF 1st)

• x = 3, x = -6

• x = 0, x = 2

• x = 2, x = 3

• x = -2, x = 1
