Question

Find the product. (r + s)^2

Answer 1

Answer is given below with explanations.

Explanation:

`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)`
