Adding Polynomials

• The degree of the polynomial is determined by the highest power of its variable(s).
• When adding polynomials, we can only combine like terms.
• The sum of two monomials is another monomial.
• When adding or subtracting polynomials, look for common factors that can be factored out.
• If there are no like terms, the result will be zero.
• Like terms have the same exponent and coefficient.
• Engineers use polynomials to graph the curves of roller coasters and bridges.
• adding and subtracting polynomials can help solve a system of equation
• Polynomials are expressions comprising a sum of terms
