Question 153038: Define the solutions to: Q(w) = w^2 � 10w + 9 @ The thing to recognize is that the equation is of a quadratic form. Hence, reverse FOIL can be easily used.
a. x = �1, �3
b. x = 1, 9 only
c. x = -1, -9 only
d. None of the above

Start with the given equation

Factor the left side

Now set each factor equal to zero:
or

or Now solve for w in each case

So the solutions are

or

This means that the answer is b) x = 1, 9 only
