Question

What must be subtracted from 4x³+16x²-x+5 to obtain a polynomial which is exactly divisible by X+5

Answer 1

divide 4x^3+16x^2-x+5 by x+5
remainder of the division is the answer

Answer 2

Answer:

90

Step-by-step explanation:

we divide 4x^3 + 16x^2 - x + 5 by (x+5)

90 comes as the remainder

so, 90 should be subtracted from the given polynomial to obtain a polynomial which is exactly divisible by x + 5.
