Question

Resolve in to factors
(1) * - ) 3x - x ) (1.6- (0.8) (iv) 5-10m - 200​

Answer 1

Answer:

(i) x × x + x × y

taking x in common,

= x(x + y)

(ii) 3 × x × x–6 × x

taking 3 x in common,

= 3x(x–2)

(iii) 2 × 0.8 × a × a–0.8 × a

taking 0.8a in common,

= 0.8a(2a–1)

(iv) 5–5 × 2 × m–5 × 4 × n

taking 5 in common,

= 5(1–2m–4n)

Answer 2

(i) x × x + x × y

taking x in common,

= x(x + y)

(ii) 3 × x × x–6 × x

taking 3 x in common,

= 3x(x–2)

(iii) 2 × 0.8 × a × a–0.8 × a

taking 0.8a in common,

= 0.8a(2a–1)

(iv) 5–5 × 2 × m–5 × 4 × n

taking 5 in common,

= 5(1–2m–4n)
