Question

Sum of two numbers is 15 , and difference of their squares is 75. What  is the  difference between that numbers.​

Answer 1

Answer:

Given:

a+b=15

a^2-b^2=75

Step-by-step explanation:

a+b=15

a^2-b^2=75 a^2-b^2=(a+b)(a-b)

(a+b)(a-b)=75

We know a+b = 15 (Given)

so,

15(a-b)=75

(a-b)=75/15

a-b=5

The difference between the numbers is 5.
