Question

Find the zeros of the polynomial 4x4 - 3x3 + 9x2 + 7x - 1

Answer 1

Answer:

let x be -1

then according to question,

4(-1)4-3(-1)3+9(-1)2+7(-1)-1

=-16+9-18+7

=16-9+7

=16-2

=14

so. we conculd that -1 is not the zeros of the polynomial.

Like this you can find more zeros by putting some values on x.
