Question

pls solve this using identity I will follow u and thank you and MARK u as BRAINLIST pls​

Answer 1

Answer:

$3x^{2}-5y^{2}$-30$x^{2}y^{2}$

Step-by-step explanation:

(3x^2-5y^2)^2

= (3x+5y)(3x-5y)^2  [Using identity a^2-b^2=(a+b)(a-b)]

OR

(3x^2-5y^2)^2

= 3x^2+5y^2-2(3x^2)(5y^2)

=$3x^{2}-5y^{2}$-30$x^{2}y^{2}$

Answer 2

Answer:

(3x²-5y²)²

3x²+5y²-2(3x²)(5y²)

3x²-5y²-30x²y²
