please show me how to solve this

(2x - 5y) power of 2

i am having a problem with the way to step by step please solve this

To solve the expression (2x - 5y)^2 step by step, we can follow these steps:

Step 1: Expand the expression using the formula (a - b)^2 = a^2 - 2ab + b^2.

Applying this formula to our expression, we have:
(2x - 5y)^2 = (2x)^2 - 2(2x)(5y) + (5y)^2

Step 2: Simplify each term within the expanded expression.

Expanding further, we have:
(2x)^2 = 4x^2
-2(2x)(5y) = -20xy
(5y)^2 = 25y^2

Thus, the expanded expression becomes:
(2x - 5y)^2 = 4x^2 - 20xy + 25y^2

So, the solution to (2x - 5y)^2 is 4x^2 - 20xy + 25y^2.

(2x - 5y)^2

(2x - 5y)(2x -5y)
(2x)(2x) + (2x)(-5y) + (-5y)(2x) + (-5y)(-5y)
4x^2 + (-10xy) + (-10xy) + 25y^2
4x^2 - 20xy + 25y^2
