What is the product of $$(x-2x)^2$$?

Evaluate: $$-3z^2(-4x^2+10z^4-4xz^5)$$

Find the value of $$(2x+5)(2x-5)$$.

Multiply: $$6x^5(-3x^4-2x^3+x^2)$$

Simplify the following expression: $$(s-r)^2-(s+r)^2$$

The value of $$-3x(5k^2+y)$$ is

Multiply: $$4x^2z(3x^2y^2-4xz)$$

Simplify: $$7a^3(-4a^4+6a^5)$$

Reduce the following expression using binomial identities: $$(3x+5)(3x+10)$$.

If $$x\Box y=(x+y)^2-(x-y)^2$$. Then $$\sqrt 4\Box \sqrt 5=$$.
