Answer 1

Given:

$(2x^5+7x^3)-(5x^2-4x^3)$

Required:

We need to find the equivalent expression of the given.

Explanation:

Distribute the minus sign.

$(2x^5+7x^3)-(5x^2-4x^3)=2x^5+7x^3-5x^2+4x^3$

Add like terms.

$(2x^5+7x^3)-(5x^2-4x^3)=2x^5+7x^3+4x^3-5x^2$$(2x^5+7x^3)-(5x^2-4x^3)=2x^5+11x^3-5x^2$

Final answer:

$2x^5+11x^3-5x^2$
