Question 353063
Please put parentheses around
- numerators
- denominators
- radicands (expressions within radicals)
- arguments to functions
- multiple term exponents
- etc.
This makes the expression clearer. Tutors are less likely to help when they have to guess what the problem is.<br>
Your problem, as you've posted it, is far too ambiguous. As it's written it means
{{{3-x/sqrt(91)-3x^2-4}}}
which is very probably not the problem you are trying to do.
