Question 1074494
.
<pre>
To answer the question, you need to solve the equation

y = 0,   i.e.

{{{x^2/10}}} + {{{9x/10}}} + {{{11/5}}} = 0.


As the first step, multiply both sides by 10 to rid of the denominators. You will get

{{{x^2 + 9x + 22}}} = 0.

Discriminant d = {{{9^2 - 4*22}}} = 81 - 88 = -7  is negative,

So the equation HAS NO real solutions.


It means that your equation does not describe the real physical situation.

          x^2/10+9x/10+11/5

Plot y = {{{x^2/10+9x/10+11/5}}}
