The sum of squares of two consecutive odd numbers is 394. Find the number
Answers
as the numbers are odd the numbers would be x and x+1. So according to the question if we solvw we will get the answer as -15 and 13. The numbers can be negative as the questiob is not saying positive odd integer
Let the one no. be x
And other no. Be ( x+2 )
A.T.Q
x²+ (x +2)²=394
x²+x²+4x +4=394
2x²+4x - 390=0
x²+2x-195 =0
Now by quadratic formula method,
D=b²-4ac
= 2²-(4)(-195)
=4+780
D=784
Now,
x = - b ± √D/2a
x = -2 ± √784/2
x= -2 +28/2. x= -2 - 28/2
x= 24/2. x= - 30/2
x=12. x= - 15
But it is rejected as odd no.
Can't be negative
Thus the no. Is 12 and other no is 15
