Hello, maybe someone could help, then I solve the equation with symbols it doesn't solve (I've attached the file), when I make simplification for my self it solve:

example p:=solve(b*x*x/2+a*As2*(x-d2)=a*As1*(d-x),x) it says no real roots

then I simplified by mysef

p:=solve(0.125x^2+0.0491x-0.01998=0, x) it give answer?

best regards,
Paulius

Alternatively you can try maple() function from the Maple Tools extension.

Hello, maybe someone could help


1. recast the functions unitless
2. plot
3. solve implicit in this case.

Hi. You need to handle units in the SMath solve function. Here it's a way.

Solve() from the Maxima plugin can handle units directly (symbolic solver)
