Math Problem Statement

The sum of the squares of two consective odd integers is 34 find the integers

Solution

Let the two consecutive odd integers be xx and x+2x + 2. According to the problem, the sum of their squares is 34: x2+(x+2)2=34x^2 + (x + 2)^2 = 34

First, expand the equation: x2+(x+2)2=x2+x2+4x+4=34x^2 + (x + 2)^2 = x^2 + x^2 + 4x + 4 = 34

Combine like terms: 2x2+4x+4=342x^2 + 4x + 4 = 34

Subtract 34 from both sides to set the equation to zero: 2x2+4x+434=02x^2 + 4x + 4 - 34 = 0 2x2+4x30=02x^2 + 4x - 30 = 0

Divide the entire equation by 2 to simplify: x2+2x15=0x^2 + 2x - 15 = 0

Next, factor the quadratic equation: x2+2x15=(x+5)(x3)=0x^2 + 2x - 15 = (x + 5)(x - 3) = 0

Set each factor equal to zero: x+5=0orx3=0x + 5 = 0 \quad \text{or} \quad x - 3 = 0 x=5orx=3x = -5 \quad \text{or} \quad x = 3

Thus, the two pairs of consecutive odd integers are:

  1. x=5x = -5 and x+2=3x + 2 = -3
  2. x=3x = 3 and x+2=5x + 2 = 5

So, the pairs of consecutive odd integers whose squares sum to 34 are 5 and 3\boxed{-5 \text{ and } -3} or 3 and 5\boxed{3 \text{ and } 5}.
