What would be the values of a, b, and c of the equation:

• a = 1

  b = 3

  c = 18

• a = x²

  b = 3

  c = 18

• a = x²

  b = 3

  c = -18

• a = 1

  b = 3

  c = -18

What is the first step to factor the given quadratic?

• Find a * c

• Find the values of a, b, and c.

• Find and factor out the GCF.

• Rewrite into standard form by adding 6 to both sides and setting it equal to 0.

• Rewrite into standard form by subtracting 6 to both sides and setting it equal to 0.

Which table is correct for the equation?

• 
• 
• 
• 

Which table is correct for the given quadratic?

• 
• 
• 

Which shows the correct factors using the table?

• (x - 5) (x - 9)

• (x - 1) (x - 9/5)

• (x - 1) (9x - 5)

• (x - 1) (5x - 9)

Factor and Solve:

• (x + 4)(x + 6)

  x = -6 and x = -4

• (2x + 3) (x - 4)

  x = -3/2 and x = 4

• (x - 4) (x - 6)

  x = 4 and x = 6

• (2x - 3) (x + 4)

  x = -4 and x = 3/2

Factor and Solve:

• 3(x - 4) (x + 8);

  x= {-8, 4}

• 3(x + 4) (x - 8)

  x= {-4, 8}

• 3(x + 4) (x + 8)

  x= {-8, -4}

• 3(x + 2) (x - 16)

  x = {-2, 16}

Factor and solve:

• (5x-9)²

  {9/5}

• (5x+9)(5x-9)

  {-9/5, 9/5}

• 25(x-9)²

  {25}

• (9x+5)(9x-5)

  {-5/9, 5/9}

Factor and solve:

• (x + 4) (x + 5)

  x = -4 and x = -5

• (x - 20) (x + 9)

  x = 20 and x = -9

• (x - 4) (x - 5)

  x = 4 and x = 5

• (x + 4) (x - 5);

  x = -4 and x = 5
