Well the vertex is the highest or possibly lowest point in a quadratic equation, the part where it hits the curve. For example imagine this is your graph--> ∩.
This graph has its vertex at the top. So when we complete the square and find the zeroes we can then find where the graph meets in the middle thus finding our vertex.

because first you got cane both of the fraction to the same denominator. 

72/80 + 70/80

Add 72+70=142.

142/80 change it to an mixed number and it will be 1 31/40 in simplest form.

A^-1/[a^-1 - b^-1] + a^-1/[a^-1 + b^-1]
o-na [289]

\dfrac{a^{-1}}{a^{-1}-b^{-1}}+\dfrac{a^{-1}}{a^{-1}+b^{-1}}=a^{-1}\left(\dfrac{a^{-1}+b^{-1}}{(a^{-1}-b^{-1})(a^{-1}+b^{-1})}+\dfrac{a^{-1}-b^{-1}}{(a^{-1}+b^{-1})(a^{-1}-b^{-1})}\right)

=a^{-1}\left(\dfrac{(a^{-1}+b^{-1})+(a^{-1}-b^{-1})}{a^{-2}-b^{-2}}\right)

=\dfrac{2a^{-2}}{a^{-2}-b^{-2}}

=\dfrac{2b^2}{b^2-a^2}

How do I solve the inequality for this: 10 < 9 + x
Firlakuza [10]
Subtract 9 from each side of the equation. so you would get 1<x. meaning that any number larger then 1 would correctly solve the equation.
