DIVIDING POLYNOMIALS Mr. Richard must have your “Un-Divided” attention for this lesson!

Algebraic long division Divide 2x³ + 3x² - x + 1 by x + 2 x + 2 is the divisor The quotient will be here. 2x³ + 3x² - x + 1 is the dividend

Algebraic long division First divide the first term of the dividend, 2x³, by x (the first term of the divisor). This gives 2x². This will be the first term of the quotient.

Algebraic long division Now multiply 2x² by x + 2 and subtract

Algebraic long division Bring down the next term, -x.-x.

Algebraic long division Now divide –x², the first term of –x² - x, by x, the first term of the divisor which gives –x.–x.

Algebraic long division Multiply –x by x + 2 and subtract

Algebraic long division Bring down the next term, 1

Algebraic long division Divide x, the first term of x + 1, by x,x, the first term of the divisor which gives 1

Algebraic long division Multiply x + 2 by 1 and subtract

Algebraic long division The remainder is –1. The quotient is 2x² - x + 1
