Step-by-step explanation:
When f(x) = 5, the x value for that would be 1.
Reading the situation, I can say that Jared and Nicole are correct because they manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. They can also write the equation as x as a function of y and substitute it to x in the other equation and solve for y. For both solution, they will still obtain the same answers.
Answer:
z=i+2
,
z=i-2
Step-by-step explanation:
Remember that the quadratic equation has the complex solutions (this is the quadratic formula).
Apply this with a=1, b=-2i and c=-5 to get:
. Then the solutions are
and
It isn't necessary to use De Moivre's formula.
