    Problem: Solve for the variables 'a' & 'b' (only the positive solutions) where,
    (a - b) x (a + b) = 9x5

    This is my work..is it correct?
    2a
    = a2 + ab -ab - b2 = 45
    a2 - b2 + b2 = 45 = b2
    a2 = 45 + b2
    a2 + a2 - b2 = 45 - b2 + b2
    a2 - b2 = 45
    7squared = 49
    -2squared = -4
    49 + -4 =45
    a = 7squared, b =
