2x^2?

Answer 6

Yes. Write that above the "2x^3" You can copy and paste my illustration, above.

Answer 7

2x^2__________________________
x+1 / 2x^3 + 4x^2 + 3x + 4

Answer 8

2x^2__________________________
x+1 / 2x^3 + 4x^2 + 3x + 4

Now multiply (x+1) by that 2x^2. Your result goes underneath "2x^3+4x^2+3x+4."

Answer 9

+2x+1 ?

Answer 10

then r=3

Answer 11

would that be right

Answer 12

Answer 13

2x^2__________________________
x+1 / 2x^3 + 4x^2 + 3x + 4



Now multiply (x+1) by that 2x^2. Your result goes underneath "2x^3+4x^2+3x+4."
