Question

special product of (2x-5y)(2x-5y)

Answer 1

both term are same so
like x*x=x^2

Answer 2

similarly it will be have power 2

Answer 3

No i am asking like 50 sq .r

Answer 4

if you are asking as to what special product is the given expression, then there are three of those for a quadratic expression namely:
1. difference of squares
e.g.
\[(a ^{2} - b ^{2}) = (a - b)(a + b)\]
2. square of sum
e.g.
\[a ^{2} + 2ab + b ^{2} = (a + b)^{2}\]
3. square of difference
\[a ^{2} - 2ab + b ^{2} = (a - b)^{2}\]

what do you think is the expression given?
