Question

Find the sum.(
`(-54x^(5)+35x^(3)-61)+(5x^(5)-69x^(3)-7)=`

Answer 1

Given: An expression

`(-54x^5+35x^3-61)+(5x^5-69x^3-7)`

Required: To find the sum of the given expression.

Step-by-step explanation: In algebraic expressions, we add or subtract only the like terms. Like terms are those terms that have the same exponents in their variable. Hence

`(-54x^5+5x^5+35x^3-69x^3-61-7)`

which gives

`(-49x^5-34x^3-68)`

Final Answer: The sum of the given expression is

`(-49x^5-34x^3-68)`
