Squaring a Binomial

Find the product:
(m+11)²

• m²+22m+121

• m²+11m+121

• m²+11m +11

• m²+22m +11

What is (2x + 6)²

• 2x² + 24x + 12

• 4x² + 24x + 36

• 2x² + 24x +36

• 4x² + 36

Find the product of:
(x-9)²

• x²-9x+81

• x²-18x+81

• x²-9x-81

• x²-18x-81

Find the product:
(7a-6)²

• 14a²-42a+36

• 14a²-84a+36

• 49a²-84a+36

• 49a²-42+36

(x + 5)² 

Hint: try (x + 5)(x + 5)

• x² + 25

• x² + 10x + 25

• x² + 10 x + 10

• x² + 10

Simplify:

(3x - 5)²

• 6x - 10

• 9x + 25

• 9x² - 30x + 25

• 9x² - 225x + 25

Your classmate was asked to square (3x + 5), he answered 9x² – 25. Is his answer correct?

• Yes, because squaring a binomial always produces a binomial product.

• Yes, because product rule is correctly applied.

• No, because the answer must be 9x² + 25.

• No, because squaring a binomial always produces a perfect square trinomial

Simplify:

(x-7)²

• x²-49

• x²+49

• x²-14x+49

• x²-14x-49

(e + 5)² 

Hint: try (e + 5)(e + 5)

• e² + 25

• e² + 10e + 25

• e² + 10e + 10

• e² + 10

(p − 8)²

• p ² − 16p − 64

• p ² + 16p + 64

• p ² − 16p − 8

• p ² − 16p + 64
