Answer:
12 and 10 and
-12 and - 10
Step-by-step explanation:
Givens
Larger number = x
Smaller number = x - 2
Equation
x*(x - 2) = 120
Solution
Remove the brackets
x^2 - 2x = 120
Subtract 120 from both sides
x^2 - 2x - 120 = 0 Factor
(x - 12)(x + 10) = 0
x - 12 = 0
x - 12 + 12 = 12
the other number is 2 less than this one or x = 10
=================
x + 10 = 0
x = - 10
The number that is 2 less than this one is
x = -10 -2
x = -12
3 = 10 because it makes sense
