Expand and simplify
(7 + V 6 )^2
Give your answer in the form b+ c V 6

55 + 14

Step-by-step explanation:

Given

(7 + )² = (7 + )(7 + )

Each term in the second factor is multiplied by each term in the first factor, that is

7(7 + ) + (7 + ) ← distribute both parenthesis

= 49 + 7 + 7 + 6 ← collect like terms

= 55 + 14

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
