Question

The sum of 2 numbers is 25. Their product is 150 find them.

Answer 1

a+b = 25, or

b = 25 -a …(1)

ab = 150, or

b = 150/a … (2_

Equate (1) and (2)

25-a = 150/a, or

-a^2+25a-150 = 0

a^2-25a+150 = 0

(a-10)(a-15) = 0

The numbers are 10 and 15.

10 = 2x5

15 = 3x5

HCF = 5. Answer.

Hope this helps!
