Question

simplify.
\\((x^2 + 5) + (3x^2 - 7x - 6)\\)

Explanation:

Step1: Remove parentheses

Since we are adding the two polynomials, we can remove the parentheses: \(x^{2}+5 + 3x^{2}-7x - 6\)

Step2: Combine like terms

For the \(x^{2}\) terms: \(x^{2}+3x^{2}=4x^{2}\)
For the constant terms: \(5-6=-1\)
The \( - 7x\) term remains as it is.
So putting it all together, we get \(4x^{2}-7x - 1\)

Answer:

\(4x^{2}-7x - 1\)
