Question

Factorise:
9x^2 –12x+3
​

Answer 1

x=1 or x=1/2

Explanation:

9x^2 - 12x +3

9x^2 -(9+3)x+3

9x^2-9x-3x+3

9x(x-1)-3(x-1)

(x-1)(9x-3)

so,

either x-1=0

x=1

or

9x-3=0

9x=3

x=3/9

x=1/2

Answer 2

9x^2-12x+3

Answer:

3(x-1)(3x-1)

Multiply the two brackets together

Check answer:

3(3x^2-x-3x+1)

3(3x^2-4x+1)

9x^2-12x+3
