Given the numerical expression:

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

Find its equivalent value.

Solution:

Since we there is a minus sign in the center of each expression, it means that we will use the operation to determine the equivalent value.

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

= 2x^5+7x^3-5x^2+4x^3

-4x^3 changes to positive since it has a minus sign in the middle, and same signs will result to a positive number, while opposite sign will result to a negative number.

Final Answer = 2x^5+11x^3-5x^2
