Find the value of a and b if 7+√5÷7-√5+7-√5÷7+√5=a+7÷11√5b


littyissacpe8b60: are you sure both values to be added. 7+√5÷7-√5 +? here it is plus or -
littyissacpe8b60: like that a + 7 ÷ is it divided or plus
littyissacpe8b60: because it will be stuck in half

 7 + √5     +    7 - √5  

 7 - √5             7 + √5


 (7 +√5)²     +   (7 - √5)²  

           7² - (√5)²


 49 + 5 +14√5  + 49 +5 - 14√5

                 44


108/44        =    a + 7√5b/11

a = 27/11

b =0

I think question is wrong no √5 comes

if Question is like this

 7 + √5     -    7 - √5  

 7 - √5             7 + √5


 (7 +√5)²     -   (7 - √5)²  

           7² - (√5)²


 49 + 5 +14√5  - 49 - 5 + 14√5

                 44

28√5/44 = 7√5/11

a + 7√5b/11

in this a = 0

b = 1
