Question

-12x+x raise to power 2 +36 factorise by identities

Answer 1

-12x+x²+36

= x²-12x+36

= (x)²- 2×x×6 + (6)²

= (x-6)² [a²-2ab+b² = (a-b)²]

Answer 2

Required Answer:-

Given to factorise:

• -12x + x² + 36

Solution:

Using identity (a - b)² = a² - 2ab + b², we will solve this problem.

Here is the solution.

-12x + x² + 36

= x² - 12x + 36

= (x)² - 2 × (x) × (6) + (6)²

Note: This is in a² - 2ab + b² form.

Therefore,

= (x - 6)²

Hence, the factorised form is (x - 6)²

Answer:

• The factorised form of the given polynomial is (x - 6)²
