Question

1. Factorise the following expressions:
i) x2 + 4x
ii) 6y3 – 3y² +9y
iii) 2(x + a) + p(x + a)​

Answer 1

Answer:

1 (x+2)^2

(x+2)(x+2)

2) Equation at the end of step 1 :

((y3) - (2•3y2)) + 9y

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

y3 - 6y2 + 9y = y • (y2 - 6y + 9)

Trying to factor by splitting the middle term

3) idk
