Can you help me simplify

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

Sure! To simplify the expression (5x^2 - 2x^3)^2, you need to square each term in the expression.

(5x^2 - 2x^3)^2
= (5x^2 - 2x^3)(5x^2 - 2x^3)
= 25x^4 - 10x^5 - 10x^5 + 4x^6
= 25x^4 - 20x^5 + 4x^6

Therefore, the simplified expression is 25x^4 - 20x^5 + 4x^6.
