Algebra 1 Section 10.1 Add and subtract polynomials A polynomial is _________________________________ ______________________________________________ _______________________________________________ Example: _________________________ The ___________ of polynomial is the largest exponent. _______ The _____________ is the coefficient of the term with the largest exponent.______ The ____________ term is the term without a variable. ______- A polynomial is in ______________ if the terms are written in descending order. Write in standard form and identify the degree, leading coefficient, and constant. 6x – 8x4 + 7 – x2 + 2x3

_________ __________ ___________ Names of polynomials Example degree classified classified by by degree number of terms 8 7x 5x + 3 x2 – 7x + 5 x3 + 9x 5x4 + 9x3 + 7x2 – x - 1 _________ __________ _________ __________ ___________

To add or subtract polynomials, add/subtract the coefficients of the similar terms. Find the sum. (2x3 + 4x2 – 6x + 8) + (8x3 – x2 + 9x – 3) Find the difference. (7x3 - 3x2 + 2x + 1) – (5x – x2 + 2 – 4x3)

Simplify (4x3 – 7x2 + 9x – 2) + (6x2 – 8x) – (x3 – 4 – x)
