lf `ax + by = 6, bx-ay = 2` and `x^2 + y^2 = 4`, then the value of `(a^2 + b^2)` would be:

if ax+by=3,bx-ay=4 and x^(2)+y^(2)=1, then the value of a^(2)+b^(2) is

If ax + by = a^(2)-b^(2) and bx + ay = 0, find the value of x + y .

If ax+by=6, bx-ay=2and x^(2)+y^(2)=4 then what is (a^(2)+b^(2)) ?

ax+by=1 bx+ay=2

If 8x ^(6) - 6 sqrt6 y ^(6) = (2x ^(2) + Ay ^(2)) ( 4x ^(4) + bx ^(2) y ^(2) + C y ^(4)), then what is the value of (A ^(2) - B ^(2) + C ^(2)) ?

ax+by=2; bx+ay=3

If (x+2) and (x-2) are factors of ax^4 + 2x - 3x^2 + bx - 4 , then the value of a + b is
