Question
A polynomial f(x) and one or more of its zeros are given. Write all numbers as integers or simplified fractions
(a) Find all the zeros.
(b) Factor f(x) as a product of linear factors.
(c) Solve the equation f(x) = 0.
f(x)=6x-17x²+22x-10; 1+i is a zero
Part: 0/6
Part 1 of 6
(a) Find all the zeros.
f(x) is a third-degree polynomial, so we expect to find three zeros (including
multiplicities). Further, note that because f(x) has real coefficients and because 1+i
is a zero, then the conjugate
must also be a zero.
This leaves only one remaining zero to find.
Part: 1/6
Part 2 of 6
One strategy is to use synthetic division twice using the two known zeros.
Divide by [x-(1-1)]. Using synthetic division, we have
Part: 2/6
Part 3 of 6
1-i

Since 1+i is a z zero of f(x), it must also be a zero of the quotient.
Divide the quotient by [x-(1+i)].
