Question

what two numbers are those sum added to the sum of their squares is 42 and whose product is 15​

Answer 1

Answer:

5,3

Step-by-step explanation:

product = 15

15=3×5

(3)(3)+(5)(5)+(5+3)= 9+25+8= 42 Hence proved

Answer 2

Step-by-step explanation:

The factors of 15 are : 1, 3, 5

Let us assume two numbers as 5 and 3

x = 5 , y = 3

(x² + y²) + (x + y)

= (5² + 3²) + (5 + 3)

= (25 + 9) + 8

= 34 + 8

= 42

Hence, Proved

5 × 3 = 15

(5² + 3²) + (5 + 3) = 42
