If a , β are the roots of `x^ 2 − 8 x + A = 0` and y , δ are the roots of `x^ 2 − 72 x + B = 0` .If a < β < y < δ are in GP,then find the digit at unit place in the value of `A + B`

The roots of x^(3)-3x-2=0 are

If x_(1),y_(1), are the roots of x^(2)+8x-20=0,x_(2),y_(2), are the roots of 4x^(2)+32x-57=0 and x_(3),y_(3), are the roots of 9x^(2)+72x-112=0, then the points,(x_(1),y_(1)),(x_(2),y_(2)) and (x_(3),y_(3)) -
