Question

If a + b is equals to 5 and a x b is equal to 6 then what is the value of a and b​

Answer 1

Answer: 2 and 3, or 3 and 2

Explanation:

a + b = 5 so a = 5 - b

Substitute a = 5 - b into ab = 6; (5 - b)b = 6

5b -
`b^(2)` = 6

`b^(2)` - 5b + 6 = 0

(b - 2)(b - 3) = 0

So b is either 2 or 3

So a is either 3 or 2 depending on what b is
