Question

Divide 3x^2-x^3-3x+5by x-1-x^2​

Answer 1

heya,

3x^2-x^3-3x+5

also , -x^3+3x^2-3x+5

x^2+x-1 ) -x^3+3x^2-3x+5 ( -x+4

- x^3 -x^2+x

________________

4x^2-4x+5

4x^2 - 4x-4

_______________

-8x+9

clearly , remainder = -8+9

quotient = -x+4

using division algorithm ,

a = b*q+r

= (x^2+x-1)(-x+4)-8+9

= -x^3+3x^2-3x+5

also , 3x^2-x^3-3x+5 ( dividend ?)

hope it may help you..
