Expand and simplify (√3+√5)^2

8 + 2

Step-by-step explanation:

Using the rules of radicals

× ⇔

× = a

Given

( + )² = ( + )( + )

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

( + ) + ( + ) ← distribute parenthesis

= 3 + + + 5 ← collect like terms

= 8 + 2

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
