Question

factorisation of 9x-12x+4

Answer 1

Step-by-step explanation:

9x^2 - 12x + 4

9x^2 - ( 6x+ 6x ) +4

9x^2 - 6x - 6x +4

3x ( 3x - 2 ) - 2 ( 3x - 2 )

( 3x - 2 ) ( 3x - 2 )

( 3x - 2 )^2 ( Optional )

Answer 2

Answer:

(3x+2) (3x+2)

Step-by-step explanation:

the given equation is 9x-12x+4

we know that 3 square is 9 and 2 square is 4

so we can say that

(3x)^2 + 2*3x*2 + (2)^2 [(a+b)^2 = a^2 + 2ab + b^]

so, (3x + 2)^2

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