Find the Factors and the Roots of each polynomial functions.

1) y = x^4 + x^3 - 7x^2 - x + 6

2) y = x^3 + 9x^2 + 15x - 25

3) y = x^4 + 4x^3 - 13x^2 - 40x + 48

4) y = x4 + 6x^3 - 9x^2 - 54x

No scam plss:(​​

Number 1 Answer;

y = (x - 2) (x - 1) (x + 1) (x + 3)

-x^4 - x^3 + 7 x^2 + x + y - 6 = 0

Roots;

x = 2

x = 1

x = -1

x = -3
