expand (x-y)^3+z^3

expand

(x - y)^{3} + z^{3}

x^{3} - 3 x^{2} y + 3 x y^{2} - y^{3} + z^{3}

Solution steps

(x - y)^{3} + z^{3}

Apply Perfect Cube Formula:

(a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3}

(x - y)^{3} = x^{3} - 3 x^{2} y + 3 x y^{2} - y^{3}

= x^{3} - 3 x^{2} y + 3 x y^{2} - y^{3} + z^{3}

(3 x^{3} \cdot y^{- 3})^{2}

893.4 \cdot 8.51969 - 8218 x

15 x y - 6 x + 5 y - 2

\frac{( a ^{2} + b ^{2} )}{( a ^{2} - b ^{2} )}

cos^{2} (x) + sin^{2} (y) cos (x^{2}) cos (x)
