Q. Perform the operation.

\newline

\left(-10 x^{2}+7 x-1\right)-\left(-5 x^{2}+5\right)

\newline

Answer:

Write Polynomials: Write down the polynomials to be subtracted. $\newline$ We have the polynomials $(-10x^{2}+7x-1$ ) and $(-5x^{2}+5$ ). We need to subtract the second polynomial from the first.
Set Up Operation: Set up the subtraction operation. $\newline$ To subtract the polynomials, we change the signs of the second polynomial and then add it to the first polynomial. $\newline$ $(-10x^{2}+7x-1) - (-5x^{2}+5)$ $\newline$ = $(-10x^{2}+7x-1) + (5x^{2}-5)$
Combine Like Terms: Combine like terms. $\newline$ Now, we add the coefficients of the like terms. $\newline$ $(-10x^{2} + 5x^{2}) + (7x) + (-1 - 5)$ $\newline$ = $(-10 + 5)x^{2} + 7x + (-1 - 5)$
Simplify Expression: Simplify the expression. $\newline$ We simplify the expression by performing the addition and subtraction. $\newline$ $(-10 + 5)x^{2} + 7x + (-1 - 5)$ $\newline$ = $-5x^{2} + 7x - 6$
