Answer 1

The sums of squares of two consecutive positive odd numbers is 290. Find the number.

$\huge\bold{\underline{Answer:}}$

$\green\bigstar$ Given:

The sums of squares of two consecutive positive odd numbers is 290

$\blue\bigstar$ To find:

Find the number.

$\purple\bigstar$ Solution:

Let the two consecutive number be x and (x+2)

According to question, we have

$\sf{:\implies x²+(x+2)²=290}$

$\sf{:\implies 2x²+4x+4=290}$

$\sf{:\implies 2x²+4x=290-4}$

$\sf{:\implies 2x²+4x=286}$

$\sf{:\implies 2(x²+2x)=286}$

$\sf{:\implies x²+2x=143}$

$\sf{:\implies x²+2x-143=0}$

$\sf{:\implies x²+13x-11x-143=0}$

$\sf{:\implies x(x+13)-11(x+13)=0}$

$\sf{:\implies (x+13)(x-11)=0}$

$\sf{:\implies x=-13}$

or,

$\boxed{\bf{\pink{⟹\:x=11}}}$

Since the number is positive,the number is x = 11

.°. x + 2 = 11 + 2 = 13

Therefore,

sum of numbers is = ( 11 + 13 ) = 24

Therefore, the number is 24
