Question

The sum of the squares of two consecutive positive numbers is 85. What is the smaller number?

Answer 1

try \(3^2+4^2\) and if that is too small, try \(4^2+5^2\) or \(5^2+6^2\)

Answer 2

@ParthKohli sum of squares

Answer 3

Let one number be: x
Next number will be: (x + 1)

So,
\[x^2 + (x +1)^2 = 85\]


\[(a + b)^2 = a^2 + b^2 + 2ab\]

Use this formula to solve this above equation...
