Divide the following expression.
RATIONALE
Start by rewriting the expression into multiple fractions with as the denominator
, use the correct signs (addition or subtraction) between the fractions.
Now that we have individual fractions, we can simplify each fraction. To do this, canc
factors in the numerator and denominator. Let's consider the first set, .
simplifies to because we can factor out from both terms. Next, conside
set, .

RATIONALE
To rewrite a quadratic equation from standard form to vertex form , we mus
perfect square trinomial relationship by completing the square. First, move the const
to the other side of the equation.
To move from the right side, subtract from both sides. Next, we can factor o
squared coefficient, , from each term on the right side of the equation because w
just .
Factoring out from each term on the right side results in . Next, inside the p
need to focus on the x-term coefficient, We will need to first divide this coefficie
square the result.
divided by equals ; squared equals . We will use this value to c
