Note common factor of 2.
The expression is the same as 2 times x^2 - 36y^2,
which is the difference of two squares and very easy to factor.
(Factors are square-root of the first term
plus or minus square-root of the second term.)

2x^2 - 72y^2
= 2 ( x^2 - 36 y^2)
= 2 (x + 6y) ( x - 6y )

2x^2 - 72y^2

First remove any common factor

2(x^2 - 36y^2)

The binomial is a difference of two squares of the form

a^2 - b^2

which factors into

(a + b)(a - b)

2(x + 6y)(x - 6y)

2x^2 - 72y^2 =
2(x^2 - 36y^2) =
2(x + 6y)(x - 6y)

first get rid of coefficients, lowest common multiple is 2.

so:
2(x² - 36y²)

= 2[(x + 6y)(x-6y)]

I'd factor it as (√2x+6√2y)*(√2x-6√2y)

hello i have the answer for you


2*(x-6*y)*(x+6*y)



hope this helps
