Solving Quadratic Equations by GCF and A=1

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

• x = 3, x = -6

• x = 0, x = 2

• x = 2, x = 3

• x = -2, x = 1

Choose the correct factored form for the quadratic expression:

x² - 12x + 27

• (x - 3)(x + 4)

• (x - 3)(x - 4)

• (x - 9)(x - 3)

• (x + 9)(x + 3)

Factor and Solve: Remember the two numbers you choose when factoring, are not your solutions to the equation!

x² + 13x + 12 = 0

• x = −12, −1

• x = 12, 1

• x = 13, 1

• x = −13, −1

What method corresponds to solve the equation n² - 2n = 0?

• Square root method

• Difference of two squares method

• GCF method

• Magic AC method

• x = -1

  x = -20

• x = 5

  x = 1

• x = 0

  x = -4

• x = 0

  x = -5

Solve:

3x² + 18x +15 = 0

Hint: Factor GCF first.

• x = 3, 2

• x = 5, 1

• x = -5, -1

• x = -3, -2

Solve for "n".

n² - 2n = 0

• n = 2 and 0

• n = -2 and 0

• n = 2

• n = 0
