\[x^2+1-5\frac{1 }{ 5}=0?\]
5 and 1/2 what does and mean? and what is the recipicle of 5?
1/5
so what does and mean?
but I don't get what the question is asking.. it says what is the reciprocal of 5 and 1/5... but how is it 5 or 1/5?
its asking what two numbers can you add together and get 5 and 1/2 or what numbers can you add together and get 5+1/2 note: 5 is the recipicle of 1/5 and vice versa
5 and 1/5*
:)
5+1/5 = 5 and 1/5 5^(-1) = 1/5
hence "the answer is stairing you in the face"
OH.... so its 5+1/5 not 5 1/5... i was thinking something differently.. thanks
s othe answer is 5 or 1/5 hahaha
So there is no real calculation needed for this question?
\[x+\frac 1x=5~\frac 15\]\[\frac {x^2+1}x=\frac {26}5\]\[x^2+1=\left(\frac {26}5\right)x\]\[x^2-\left(\frac{26}5\right)x+1=0\] \[x_{1,2}=\frac{-(-\frac{26}5)\pm\sqrt{(-\frac{26}5)^2-4}}{2}\]\[\qquad=\frac{\frac{26}5\pm\sqrt{\frac{676}{25}-4}}{2}\]\[\quad=\quad...\]
x+ 5/26
