Help the Poor Math Student 

Vocabulary Dividend: number being divided Divisor: number you are dividing by Quotient: is number you get when you divide Remainder: the number left over if it does not divide evenly Factors: the DIVISOR and QUOTIENT are FACTORS if there is no remainder

Steps for Dividing

Long Division Divide WITHOUT a calculator!! 1. 2.

Using Long Division on Polynomials

Remainder Theorem Remainder Theorem: If a polynomial P(x) is divided by (x – a), where a is a constant, then the remainder is P(a).

Using the Remainder Theorem Find P(-4) for P(x) = x 4 – 5x 2 + 4x + 12.

Is 7 a factor of 100?

Remainder Theorem Given some polynomial divided by (x – a), if the remainder is 0 then (x – a) is a FACTOR!

Is x – 1 a factor?

Is x – 3 a factor?

Exit Ticket On a half sheet of paper pick two of the four to divide. You must use synthetic division on one and polynomial long division on one!
