Hello, let's have a look on the question.
00:03
So we have f of x is equal to x -cube minus 14x square plus 66x minus 104.
00:11
So this is the equation and one root is given to us, that is 5 minus iota.
00:18
So whenever we have complex roots, it always comes in a pair.
00:22
So the conjugate of this conjugate will be equal to 5 plus iota.
00:27
So these both are the root.
00:29
Two roots of equation are both of them are the roots of equation.
00:36
So 5 minus iota and 5 plus iota.
00:40
Now, this is, we can say the factor of this equation f of x, that 5 minus 5 plus iota and x minus 5 minus aota are factors are factors of f of x.
00:59
Because 5 minus iota and 5 plus iota are the roots...
