Question

I will mark you as the brainlist is younans my question If a+b=5 ab=6 Find a square + b square​

Answer 1

Answer:

Step-by-step explanation:

(a+b)² = a² + b² + 2ab

∴ a² + b² = (a+b)² - 2ab

a² + b² = 5² -2 x 6

a² + b² = 25 - 12

a² + b² = 13

Hope it helps and please mark as brainliest

           

Answer 2

Answer:

Step-by-step explanation:

Since, a+b=5

So, a=5-b

And ab=6

So, b=6/a

Solution:-

$a^{2} +b^{2}$

$(5-b)^2+(6/a)^2\\25+b^{2}-10b +36/a^{2}$

Substituting the values and simplifying u ll get your required solution.

Thanks!
