The given function is

We simplify to get;

This function is equal to zero when

QUESTION 2

The given function is

We factor to get;

This function equals zero when

QUESTION 3

The given function is

We factor to get,

The function equals zero when

Hence the equation has no real roots.

The complex roots are

or

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632
