Example 11 : Find two consecutive odd positive integers, sum of whose squaresis 290. About the author Jade
Answer: Let x an odd positive integer Then, according to question x² + ( x + 2 ) = 290 2x² + 4x – 286 = 0 x² + 2x − 143=0 x² + 13x − 11x − 143=0 ( x +13 ) ( x + 11 ) = 0 x = 11 as x is positive Hence required integers are 11 and 13. Step-by-step explanation: I hope it’s helpful for you. Reply
Answer:
Let x an odd positive integer
Then, according to question
x² + ( x + 2 ) = 290
2x² + 4x – 286 = 0
x² + 2x − 143=0
x² + 13x − 11x − 143=0
( x +13 ) ( x + 11 ) = 0
x = 11 as x is positive
Hence required integers are 11 and 13.
