Question

By using remainder theorem divide x⁴

- 5x²

- 4x by x + 3 and find the

remainder.

Solution – p(x) = x⁴


- 5x²

- 4x , divisor = x + 3 ∴ take x = - 3

∴ remainder = p(-3) = (-3)4 – ……. – 4(-3)……(by remainder theorem)

= (…..) - ……. + 12

p(-3) = ……

∴ Remainder = ……..​

Answer 1

Answer:

48

Step-by-step explanation:

given equation,

p(x) = x⁴- 5x²- 4x

now, if (x+3) is a factor of p(x)

then,

p(-3) = (-3)⁴-5*(-3)²-4*(-3) = 81 - 45 + 12 = 48.

∴ Remainder = 48.
