Question

What must be subtracted from 4x^4-3X^3+2X^2+13X-4 , SP RESULT CAN BE DIVIDED BY X+1

Answer 1

Answer:-8

Step-by-step explanation:

Answer 2

Answer:

$4 {x}^{4} - 3 {x}^{3} + 2 {x}^{2} + 13x - 4 =$

$4 {x}^{4} + 4 {x}^{3} - 7 {x}^{3} - 7 {x}^{2} + 9 {x}^{2} + 9x + 4x + 4 - 8 =$

$4 {x}^{3} (x + 1) - 7 {x}^{2} (x + 1) + 9x(x + 1) + 4(x + 1) - 8 =$

$(x + 1)(4 {x}^{3} - 7 {x}^{2} + 9x + 4) - 8$

i.e -8 should be subtracted for perfect division.

2nd method.....

putting X = -1 in polynomial

we get - 8
