Question

solve x^3-7x^2+159x-9=0 by synthetic division​

Answer 1

Step-by-step explanation:

Explanation:

Because (a - b + c - d) = 0, then f(-1) = 0. One factor is (x + 1).

After division -->

#f(x) = (x + 1)(x^2 + 6x + 9) =#

#f(x) = (x + 1)(x + 3)^2#

Answer 2

Because (a - b + c - d) = 0, then f(-1) = 0. One factor is (x + 1).

After division -->

f(x)

=

(x+1)(x2+6x+9)=

f(x)=(x+1)(x+3)

x=-1,-3
