Answer provided by our tutors
let 'x' and 'y' be the numbers and x>y
one number is six larger than another number
x = y + 6
the square of the larger number is 132 greater than the square of the smaller number.
x^2 = 132 + y^2
plug x = y + 6 into the previous equation
(y + 6)^2 = 132 + y^2
by solving we find
y = 8
