Prove that on dividing the polynomia 4x3 +3x2 +2x-9 by x-1 the remaind

1.	Prove that on dividing the polynomia 4x3 +3x2 +2x-9 by x-1 the remainder is zero
Answer» If the remainder is zero, it is divisible by x-1. → 4x³+3x²+2x-9 = (x-1)Qₓ+R To remove Qₓ, LET's multiply zero in FRONT of it. It is REQUIRED that x-1=0 now. (x=1) → 4+3+2-9 = 0Qₓ+R → 0 = R It is divisible by x-1.

Prove that on dividing the polynomia 4x3 +3x2 +2x-9 by x-1 the remainder is zero

Answer»

If the remainder is zero, it is divisible by x-1.

→ 4x³+3x²+2x-9 = (x-1)Qₓ+R

To remove Qₓ, LET's multiply zero in FRONT of it. It is REQUIRED that x-1=0 now. (x=1)

→ 4+3+2-9 = 0Qₓ+R

→ 0 = R

It is divisible by x-1.
