Question

Consider the polynomial P(x)=x⁴+3x³-28x²-36x+144.Is 1 a zero of the polynomial P?

Answer 1

As the P(1) is not zero so 1 will not be zero of the polynomial

Explanation:

We have given polynomial
`x^4+3x^3-28x^2-36x+144`

We have to find that is 1 is zero of the polynomial

If 1 will be zero of polynomial then
`p(1)` will be zero

As
`P(1)=(3)^4+3* (1)^3-28* (1)^2-36* 1+144=1+3-28-36+144=84`

As the P(1) is not zero so 1 will not be zero of the polynomial
