Question
Adding and Subtracting Polynomials Find the sum, difference, or product.$$\left(5 x^{3}+4 x^{2}-3 x\right)-\left(x^{2}+7 x+2\right)$$
Step 1
This changes the sign of each term in the second polynomial. So, we have: $$\left(5 x^{3}+4 x^{2}-3 x\right)-\left(x^{2}+7 x+2\right) = 5 x^{3}+4 x^{2}-3 x - x^{2} - 7 x - 2$$ Show more…
