Question

factors of 27- 8x^3 are
which is the correct ans
(a) (3-2x) ( 9+6x+4x^2)
(b) (3-2x) ( 9-6x+4x^2)
(c) ( 3-2x) ( 9+6x-4x^2)
(d)None off these​

Answer 1

Answer:

(i) 12x = 2 × 2 × 3 × x

36 = 2 × 2 × 3 × 3

The common factors are 2, 2, 3.

And, 2 × 2 × 3 = 12

(ii) 2y = 2 × y

22xy = 2 × 11 × x × y

The common factors are 2, y.

And, 2 × y = 2y

(iii) 14pq = 2 × 7 × p × q

28p2q2 = 2 × 2 × 7 × p × p × q × q

The common factors are 2, 7, p, q.

And, 2 × 7 × p × q = 14pq
