Question

For the polynomial below, −1 is a zero.
g(x)=x^3 - 5x^2 + x + 7
Express g(x)as a product of linear factors.

Answer 1

given that -1 is a zero of this polynomial - so what mean this ?

Answer 2

you divide g(x) by -1

Answer 3

not exactly

this mean that g(x) is divisible by (x+1)
yes ?

Answer 4

yes

Answer 5

so try divide it by (x+1) and will get the right answer sure

Answer 6

yea division by x+1 will give you a trinomial in x^2 which you can factor

Answer 7

ty. welsh. for your explain - i think can using long division too - yes ?

Answer 8

i dont know how to divide it

Answer 9

yes or synthetic division. I prefer long division.

Answer 10

yes i prefer it same with you too
