ab=0.36
b=0.36/a...........(1)
a-b=0.9
a-0.36/a=0.9
a²-0.9a-0.36=0
a=[0.9±√(0.81-4(-0.36))]/2
a=1.2 or -0.3
b=0.3 or -1.2
Using any value of a&b
You can find a²-b²
b=0.36/a...........(1)
a-b=0.9
a-0.36/a=0.9
a²-0.9a-0.36=0
a=[0.9±√(0.81-4(-0.36))]/2
a=1.2 or -0.3
b=0.3 or -1.2
Using any value of a&b
You can find a²-b²
