Simplify the fraction and state the excluded value(s).

Answer:

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10} = \frac{7x - 10}{5}, x \neq -2$

Discontinuities

Removable (Holes)
Jump (Piece-wise functions)
Infinite (Asymptotes)

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10}$

Step 2: Simplify

[Frac - Numerator] Factor quadratic: $\displaystyle \frac{(7x - 10)(x + 2)}{5x + 10}$
[Frac - Denominator] Factor GCF: $\displaystyle \frac{(7x - 10)(x + 2)}{5(x + 2)}$
[Frac] Divide/Simplify: $\displaystyle \frac{(7x - 10)}{5}, x \neq -2$

When we divide (x + 2), we would have a removable discontinuity. If we were to graph the original function, we would see at x = -2 there would be a hole in the graph.

Find two consecutive whole numbers such that the sum of their squares is 221.

Law Incorporation [45]

$n^2+(n+1)^2=2n^2+2n+1=221$
$2n^2+2n=220$
$n^2+n=110$
$n^2+n-110=0$
$(n-10)(n+11)=0\implies n=10,n=-11$

But since $n$ must be a whole number, we ignore $n=-11$ . So the two integers are $n=10$ and $n+1=11$ .
