Question

The difference of the squares of two positive consecutive even integers is 68 find the integers use the fact that if X represents an even integer then X +2 represents the next consecutive even integers

Answer 1

Answer:

16 and 18

Step-by-step explanation:

Here, x represents the even integer then the even consecutive next integer is x + 2,

According to the question,

$(x+2)^2-x^2=68$

$x^2+4x+4-x^2=68$  ( Using (a+b)² = a² + 2ab + b² )

$4x+4=68$                 ( Combining the like terms )

$4x=64$

$\implies x = \frac{64}{4}=16$

Hence, first integer = 16,

Second integer = 16 + 2 = 18.

Answer 2

The two positive consecutive integers we'll call x and x+2. then (x+2)² - x² =68
x²+4x+4-x²=68
4x=64
x=16

the integers are 16 and 18
