I interpret your problem to involve solving for c in the equation:
.
.
square both sides to get:
.
.
get this into the standard quadratic form by subtracting 3C - 8 from both sides so that the
right side becomes zero. With this subtraction you get:
.
.
This does not factor nicely so use the quadratic formula to solve. In the quadratic
formula you know that for an equation of the form:
.
.
the values of x that satisfy this equation (or in other words, the answers) are:
.
.
For your problem x = C, and by comparison with the standard form, a = 1, b = -3, and c = 8.
Substitute these values into the answer form and you get:
.
.
which simplifies to:
.
.
and by working on the radical you get:
.
.
and by substituting under the radical the two answers become:
.
.
Hope I interpreted the problem correctly and that this clarifies the problem for you.
