Hope I can help! ;)
Answer: the numbers are 9 and 2
Step-by-step explanation:
Let the numbers be a and b
a + b = 11.........equation 1
ab = 18.......equation 2
Multiply equation 1 by a
a ^2 + ab = 11a.......equation 3
Substitute the value of ab from equation 2 into equation 3
a ^2 + 18 = 11a
a^2 - 11a + 18 = 0
(a-9) x (a-2) = 0
If a = 9, then b =2
