Question 51 Factorization of Polynomials Exercise 3C

𝑥^2 − 2𝑥 + 7/16

Answer:

𝑥^2 − 2𝑥 + 7/16

We can further write it as

= 1/16(16𝑥^2 − 32𝑥 + 7)

= 1/16(16𝑥^2 − 4𝑥 − 28𝑥 + 7)

By taking out the common terms

= 1/16[4𝑥 (4𝑥 − 1) − 7(4𝑥 − 1)]

So we get,

=1/16(4𝑥 − 7)(4𝑥 − 1)

= (4x – 1) ( 𝑥/4−7/16)
