x^2 -15x +54 = 0 for you can factor it easy just you need getting two numbers with sum equal -15 and product equal 54
-15= (-9)+(-6) and (-9)*(-6)= -54 in this way will get
x^2 -15x +54 = (x-6)(x-9)
hope helped

54 can be formed by 9*6 or -9*-6
So the equation X^2-15x+54 can be factored into:
(x -9) * (x -6)
