Perfect Square Polynomials

What isn't this quadratic a

Difference of Squares?

• It's not a difference

• 2 is not a perfect square

• 49 is not a perfect square

• Silly goose, it is a difference of squares!

• x² is not a perfect square

TRUE or FALSE. The 2nd term shows that it is 2 times of the answer when you multiply the factor of perfect squares ,x² and 16.

x² +8x + 16

• TRUE

• FALSE

Answer explanation

It is true.

x² + 8x + 16

Let's get the factor of the

x² = x • x

16 = 4 • 4 or -4 • -4

Choose 4 because of positive on 8 .

2 times 4 times x is 8x.

x² + 8x + 16

Factor Completely: 4x² - 20x + 25

• (4x - 25) (x -1)

• (2x + 5) (2x - 5)

• (2x - 5)²

• (4x - 5) (x - 5)

Factor
v² - 6v + 9

• (v-3)²

• (v-6)²

• (v-9)(v+6)

• not factorable

Factor: x² - 4x + 4

• (x + 2)²

• (x - 2)²

• (x + 4)²

• (x - 4)²
