Question

Please give me correct answer.
factorise 121x^2-264x+144
​

Answer 1

Answer:

(11x + 12) • (11x - 12). is the answer

Answer 2

Step-by-step explanation:

Given polynomial is 121x²-264x+144

It can be written as

(11x)²-2×11x×12+12²

This is in the form of a²-2ab+b²

we know that a²-2ab+b²=(a-b)²=(a-b)(a-b)

(11x)²-2×11x×12+12²

=>(11x-12)²

=>(11x-12)(11x-12)

121x²-264x+144=(11x-12)(11x-12)
