Answer is given below with explanations.
Step-by-step explanation:
[tex]we \: know \: that \: {(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} \\ to \: find \: : {(r + s)}^{2} \\ by \: the \: above \: mentioned \: formula \\ we \: get \: the \: answer \\ {(r + s)}^{2} = {r}^{2} + 2rs + {s}^{2} \\ hence \: the \: product \: is \: {r}^{2} + 2rs \: + {s}^{2} [/tex]
