-Fold a sheet of paper in half (hamburger) then in half again (hotdog). -Label the four sections that are created: Monomials, Binomials, Trinomials, Polynomials
3
Adding and Subtracting Polynomials
4
SWBAT write polynomials in standard form. SWBAT add and subtract polynomials. Students will construct viable arguments and critique the reasoning of others.
5
The degree of a monomial is the sum of the exponents of all of its variables. The degree of a polynomial is the greatest degree of any term in the polynomial. DegreeName 0Constant 1Linear 2Quadratic 3Cubic 4Quartic 5Quintic 6 or more6 th degree, 7 th degree, and so on.
6
ExpressionPolynomial?Degree?Special Name? a) 4y – 5xz b) -6.5 c) 7a -3 + 9b d) 6x 3 + 4x + x + 3
7
ExpressionPolynomial?Degree?Special Name? a)x b) -3y 2 – 2y + 4y - 1 c) 5rx + 7tuv d) 10x -4 – 8x a
8
The standard form of a polynomial has the terms in order from greatest to least degree. In this form, the coefficients of the first term is called the leading coefficient. Write each polynomial in standard form. Identify the leading coefficient. a) 3x 2 + 4x 5 – 7x b) 5y – 9 – 2y 4 – 6y 3
9
a) 8 – 2x 2 + 4x 4 – 3x b) y + 5y 3 – 2y 2 – 7y 6 + 10

11
Find each sum: a) (2x 2 + 5x – 7) + (3 – 4x 2 + 6x) b) (3y + y 3 – 5) + (4y 2 – 4y + 2y 3 + 8)
12
a) (5x 2 - 3x + 4) + (6x – 3x 2 – 3) b) (y 4 -3y + 7) + (2y 3 + 2y – 2y 4 -11)
13
Find each difference: a) (3 – 2x + 2x 2 ) – (4x – 5 + 3x 2 ) b) (7p + 4p 3 – 8) – (3p 2 + 2 – 9p)
14
a) (4x 3 – 3x 2 + 6x – 4) – (-2x 3 + x 2 -2) b) (8y -10 + 5y 2 ) – (7 – y 3 + 12y)
