Question

If a+b= 5 and ab= 6 than a to the power 2+b to the power 2​

Answer 1

ANSWER⭐⭐❣❣

a+b=5...(1)

ab=6....(2)

from eq.(1)

a=5-b....(3)

substitute this value in eq.(2)

(5-b)b=6

b^2-5b-6=0

b^2-3b-2b-6=9

b(b-3)-2(b-3)

(b-3) and (b-2)

b=3 and b=2

if b=3 then a=2

if b=2 then a=3

now, a^2+b^2=3^2+2^2

9+4=13
