Input:

Result:

On this page, you can expand, factor, and simplify polynomials.
Variable names can be subscripted with underscores, such as V_th.
Single-case, uppercase letters C,E,N,O,Q and S are not allowed in variable names.
Math function names such as sin, atan, fft, fu, Matrix, etc. cannot be variable names.
j,i,I are all replaced by j and treated as imaginary units.
If you add subscripts to i and I, as in I_D, V_i, they are not substituted for j and are not treated as imaginary units.
You can test how input characters are interpreted on the page "Evaluate Expressions".

Input	Evaluation	Description
`(x+1)*(x-1)`	$(x + 1) (x - 1)$	`*` cannot be omitted.
`10**2`	$10^{2}$	`**` is a power.
`j*j`	$- 1$	`j` is an imaginary unit.
`i*V`	$j V$	`i` is replaced by `j`.
`(A+1)/2*B`	$\frac{(A + 1)}{2} B$	Different from below.
`(A+1)/(2*B)`	$\frac{(A + 1)}{(2 B)}$	Different from above.
