Division by Zero

In mathematics division with zero is undefined (odefinierat).

We don't know the answer to this equation: \frac{5}{0} = Undefined

Therefore, if we see an equation that looks like this: \frac{5x}{x-6}

(The equation has an variable in the denominator, nämnaren, nedanför)

Quadratic Equations:

Perfect square trinomial (Positive):

General: (a+b)^2 = a^2+2ab+b^2

In Use: (x+6)^2 = x^2+2(x\times6)+6^2=x^2+12x+36

Explanation:  (x+6)^2 = (x+6)(x+6)= x^2+6x+6x+36

(x+6)^2 =x^2+12x+36
