Question

Factorise fully the following: a) x² + 3x b) 2x? - 8x c) 6x + 9x d) 12x - 4x?

Answer 1

Answer:

a) $x(x+3)$

b) $2x(x-8)$

c) $3x(2+3x^{2})$

d) $4x^{2} (3x-1)$

Step-by-step explanation:

a) $x^{2} +3x=x(x+3)$

b) $2x^{2} -8x=2x(x-8)$

c) $6x+9x^{3} =3x(2+3x^{2})$

d) $12x^{3} -4x^{2} =4x^{2} (3x-1)$
