Hello,
Is there any way to solve an equation containing a combination of ‘x’ square, ‘x’ and under root ‘x’ along with other coefficients?
Or can we solve two coupled equations via Mathematica at once?
Plz reply soon.
Can you post the equation?
These show up in a simple web search.
Thanx, but this thing don’t work. I have tried lot.
You have not given any indication of what you have tried. You have not even given a clear description of what it is you want.
Rules of thumb for posting questions: Be clear. Give examples., Provide whatever code you have tried. Don’t make people guess as to what it is that’s being asked.
Hi,
Daniel is quite right: a clear description of the problem would help. You say:
solve an equation containing a combination of ‘x’ square, ‘x’ and
under root ‘x’ along with other coefficients
This following equation has x^2, x and \sqrt{x} with a couple of coefficients and solves just fine:
NSolve[2 x^2 - x + 3 Sqrt[3 x] - 2 == 0, x]
(*{{x -> -0.847034 + 1.29585 I}, {x -> -0.847034 - 1.29585 I}, {x -> 0.164977}}*)
Even for the general form you get an analytical solution if you want:
Solve[a x^2 + b x + c Sqrt[d x] - 2 == 0, x]
Here is the first of the solution Solve finds:
So these guys are a bit long.
Solve[a x^2 + b x + c Sqrt[d x + e] + g == 0, x]
evaluates in about 4/100 of a second on my machine. So without further specification of the problem it will be difficult to help.
Best wishes,
Marco
Sorry, I am new here. Sorry once again. My whole equation is attached here in a mathematica file, and an example is given as
x^2(4pqr + 3nr - …) - Sqrt[64 x a^8 e^2 M^6 Q^2 r^8 - 128 x^2 a^7 e G L M^6 Q r^7]+ x(5lm + n/q -q/m …) + Sqrt[ x a e M^4 Q^2 r^8 - 55 x^2 a^7 e G L M^6 Q r^7]…
A number of under root expressions containing x, x^2 etc too. So please help.
So sugest me any to solve my equation. Thanks a lot,
Equation is attached here. I have to solve this equation for L.
Thanks.
