Question

factorise the following 9 X square + 18 x + 8​

Answer 1

Answer:

9x^2+18x+8=0

9x^2+6x+12x+8=0

3x(3x+2)+4(3x+2)=0

(3x+4)(3x+2)=0

x=-4/3. or. x=-2/3

Answer 2

Answer:

9x^2 + 18 x + 8

split the middle term 18x as (6x + 12x).

=> 9x^2 + 6x + 12 x + 8

=> 3x (3x + 2) + 4 (3x + 2)

= (3x + 4) (3x + 2)
