If H.C.F. and L.C.M. of two quadratic expression are (x-5) and x3 - 19...
Since (x - 1) is the highest common factor between them, let the expressions be (x - 1)(x - a) and (x - 1)(x + b).

Now the least common multiple of these two expressions will be,
(x - 1)(x - a)(x - b) = x3 - 19x - 30
So 1,a,b are the roots of the given cubic equation
1 + a + b = 0 => a + b = -1
(1)(a)(b) = -30 => ab = -30
On solving the two equations we get a = 5, b = -6

Therefore the expressions are (x - 1)(x - 5) and (x - 1)(x + 6)
