Question 29 Factorization of Polynomials Exercise 3B

9𝑎^2 + 6𝑎 + 1 − 36𝑏^2

Answer:

9𝑎^2 + 6𝑎 + 1 − 36𝑏^2

We can further write it as

= (9𝑎^2 + 6𝑎 + 1) − 36𝑏^2

So we get

= [(3𝑎)^2 + 2 × 3𝑎 × 1 + 1^2] − (6𝑏)^2

= (3𝑎 + 1)^2- (6𝑏)^2

Based on the equation 𝑎^2 − 𝑏^2 = (𝑎 + 𝑏)(𝑎 − 𝑏)

We get,

= (3a + 1 + 6b) (3a + 1 – 6b)
