Question

factorise 81x^-72xy+12x ​

Answer 1

Answer:

We first factorize each term of the given polynomial 8x

2

−72xy+12x as shown below:

8x

2

=2×2×2×x×x

72xy=2×2×2×3×3×x×y

12x=2×2×3×x

The common factors of 8x

2

,72xy and 12x are 2,2 and x, therefore, the HCF is:

2×2×x=4x

Thus, taking out the HCF, we have:

8x

2

−72xy+12x=4x(2x−18y+3)

Hence, 8x

2

−72xy+12x=4x(2x−18y+3).
