Question

Subtract the polynomials: (6x3 - 4x + 2) - (2x3 - 1). Enter your answer as a polynomial in descending order below, and use the caret (^) for exponents. For example, you would write as 4x^2.

Answer 1

the negative becomes positive and everything in the parenthesis is now a negative. (6x^3-4x+2) +(-2x^3-1)= 4x^3+4x+1
