Formula use: \left(a+b\right)^3=a^3+3.a^2.b+3.a.b^2+b^3
Here, given expression is : x+yz
Find the cubes with the help of formula :
\rightarrow\left(x+yz\right)^3
\rightarrow\left(x\right)^3+3.\left(x\right)^2.yz+3.x.\left(yz\right)^2+\left(yz\right)^3 [use formula]
\rightarrow x^3+3x^2yz+3xy^2z^2+y^3z^3
Ans: x^3+3x^2yz+3xy^2z^2+y^3z^3\ .
