Question

Sum of two numbers is 25 and their multiply is 144 what is different

Answer 1

Step-by-step explanation:

By different, i guess you mean difference

POINT TO REMEMBER:--

Always try to convert the numbers into equation in one variable to keep the calculation convinient

Let the 1st number be x

Then the 2nd number is (25 - x)

According to the question,

1st number × 2nd number = 144

x × (25 - x) = 144

25x - x^2=144

x^2 - 25x + 144 = 0

x^2 - 9x - 16x + 144 = 0

x(x - 9) - 16(x - 9) = 0

(x - 9)(x - 16) = 0

x = 9 ,16

So, the numbers are 16 and 9 or 9 and 16

Hence, difference = 16 - 9 or 9 - 16

= 7 or -7

Hope that helps....
