Today in Algebra 2• Please get out worksheets from
past two days:Polynomial Long Division (one was white and one was pink)

Dividing Polynomials1) Divide first terms (put answer on top)2) Mulitply answer from step 1 with term on
outside(the divisor).3) Subtract (or change signs of bottom line
and add)4) Bring down at least the next term5) Repeat steps 1-4 until exponent in
bottom line is less than the exponent in the term on the outside (the divisor)
