Question 52 Factorization of Polynomials Exercise 3C

1/3𝑥^2 − 2𝑥 − 9

Answer:

1/3𝑥^2 − 2𝑥 − 9

We can further write it as

=1/3𝑥^2 − 3𝑥 + 𝑥 − 9

By taking out the common terms

= 𝑥 (𝑥/3− 𝑥) + (𝑥 − 9)

=𝑥/3(𝑥 − 9) + (𝑥 − 9)

Taking (x – 9) as common

= (x – 9) (𝑥/3+ 1)

So we get,

= (x – 9) (𝑥+3/3)

=1/3(𝑥 − 9)(𝑥 + 3)
