Full solution

Q. Perform the operation.

\newline

\left(7 x^{2}-9 x\right)+(7 x-1)

\newline

Answer:

Identify Polynomials: Identify the polynomials to be added. $\newline$ We have two polynomials: $7x^{2}-9x$ and $7x-1$ . We need to add these polynomials together.
Align Like Terms: Align the like terms. $\newline$ When adding polynomials, we combine the like terms. The like terms are those that have the same variable raised to the same power.
Perform Addition: Perform the addition. $\newline$ $(7x^{2}-9x) + (7x-1)$ $\newline$ Combine the $x^2$ terms: $7x^{2}$ (there are no other $x^2$ terms to combine with). $\newline$ Combine the $x$ terms: $-9x + 7x$ . $\newline$ Combine the constant terms: $-1$ (there are no other constant terms to combine with).
Simplify Expression: Simplify the expression. $\newline$ $(7x^{2}-9x) + (7x-1) = 7x^{2} + (-9x + 7x) - 1$ $\newline$ $= 7x^{2} - 2x - 1$
