multiply
what two operations can require the box method
division and multiplications
(x2-x+5)+(6x2+2x-10)
what is the first thing you do
combine like terms
(3x2-8x+7)-(2x2-6x+12)
what is the first step
rewrite as addition
what are to methods of solving dividing polynomials?
box and synthetic
2xy(3x2y+4xy-5xy2)
what do you do with the 2xy
distribute
x2+6x2=
7x2
3x2 () -2x
what goes in the blank?
addition sign
(x2-2x2-5x+6)/(x-3)
what is the first step in synthetic division?
bring the 3 out and make sure its positive
2xy(3x2y)=
6x3y2
-x+2x
x
- -2x2+6x-12
what is the mistake in this problem
there is a minus sign instead of an addition sign
(x3-2x2-5x+6)/(x-3)
what is the second step
bring all the numbers down
2xy(3x2y+4xy-5xy2)
what do you get after you distribute
6x3y2+8x2y2-10x2y2
(x2-x+5)+(6x2+2x-10)=
7x2+x-5
(3x2-8x+7)-(2x2-6x+12)=
x2-2x-5
1x2+1x-2
how do you get this solution?
bring the one down then multiply
6x3y2+8x2y2-10x2y3=
what is the answer
0
7x2+x-5
what is the final answer?
there is no final answer after that
what is the next step after changing the sign
combine like terms
