Expressions involving conjugates are combined by applying the following transformations:

In 2-D Math, the conjugate of an expression is depicted by a horizontal bar above the expression.

$\mathrm{combine}\left(\stackrel{\&conjugate0;}{x}\+\stackrel{\&conjugate0;}{y}\,\mathrm{conjugate}\right)$

$\stackrel{\&conjugate0;}{\left(x+y\right)}$

$\mathrm{combine}\left(\stackrel{\&conjugate0;}{x}\+{\stackrel{\&conjugate0;}{x}}^2\+\stackrel{\&conjugate0;}{x^3}\,\mathrm{conjugate}\right)$

$\stackrel{\&conjugate0;}{\left(x^3+x^2+x\right)}$

$\mathrm{combine}\left({\stackrel{\&conjugate0;}{x}}^3\+3\stackrel{\&conjugate0;}{y}\stackrel{\&conjugate0;}{z}\,\mathrm{conjugate}\right)$

${{\stackrel{\&conjugate0;}{x}}^{}}^3+3\stackrel{\&conjugate0;}{\left(yz\right)}$

$\mathrm{combine}\left({\stackrel{\&conjugate0;}{x}}^3\+\stackrel{\&conjugate0;}{y}\stackrel{\&conjugate0;}{z}\,\mathrm{conjugate}\right)$

$\stackrel{\&conjugate0;}{\left(x^3+yz\right)}$
