Question

Factorise - a) 8n - 50 b) 4x? + 8x - 5 c) 18x - 32x d) 3x - 10x + 8​

Answer 1

Answer:

Concept used:

The method of writing the given polynomial into product of its factors is

called factorization.

a.

$8n-50$

$=2(4n-25)$

b.

$4x^2+8x-5$

$=4x^2+10x-2x-5$

$=2x(2x+5)-1(2x+5)$

$=(2x-1)(2x+5)$

c.

$18x^2-32x$

$=2x(9x-16)$

d.

$3x^2- 10x + 8$

$=3x^2- 6x-4x+ 8$

$=3x(x-2)-4(x-2)$

$=(3x-4)(x-2)$
