Question

(2xpower 2-5ysquare )(5x+2y square)

Answer 1

Your question is (2x)²-(5y)²(5x+2y)²
Here we use two formulas, a²-b²=(a+b)(a-b)
and other is, (a+b)²=a²+b²+2ab
now solution,
(2x)²-(5y)²(5x+2y)²=0
(2x+5y)(2x-5y)(25x²+4y²+20xy)=0
(4x²-10xy+10xy-25y²)(25x²+4y²+20xy)=0
(4x²-25y²)(25x²+4y²+20xy)=0
100x⁴+16x²y²+80x³y-625x²y²-100y⁴-500xy³=0
100x⁴-100y⁴-609x²y²+80x³y-500xy³=0
your solution may be again!!!!!
