left(3 x^{2}+2 xright)-left(8 x^{2}+7right)

Question

Accepted Answer

Step:1 ：Given the polynomials (3 x^{2}+2 x) and (8 x^{2}+7)Step:2 ：We are asked to subtract the second polynomial from the firstStep:3 ：To do this, we subtract the like terms separatelyStep:4 ：Subtracting the coefficients of (x^{2}) terms gives us (-5x^{2})Step:5 ：Subtracting the constant terms gives us (-7)Step:6 ：The term (2x) remains unchanged as there is no corresponding term in the second polynomialStep:7 ：So, the result of the subtraction is (-5x^{2} + 2x - 7)Step:8 ：Final Answer: (boxed{-5x^{2} + 2x - 7})
