Question

Perform the indicated operation by removing the parentheses and combining like terms.(5x + 3) + (x2 – 8x + 4)

Answer 1

`x^2-3x+7`

Explanations:

Given the sum of the functions expressed as:

`\mleft(5x+3\mright)+x^2-8x+4`

Collecting the like terms:

`x^2+5x-8x+3+4`

Group the terms based on their degrees

`x^2+(5x-8x)+(3+4)`

Simplify the result to determine the final answer:

`\begin{gathered} x^2+(5x-8x)+(3+4) \\ x^2+(-3x)+7 \\ x^2-3x+7 \end{gathered}`

Hence the required sum of the functions is x^2 - 3x + 7
