दो क्रमागत धनात्मक पूर्णांकों के वर्गों का योग (145) है। यदि छोटा पूर्णांक (x) है, तो समीकरण कौन-सा है?
The sum of squares of two consecutive positive integers is (145). If the smaller integer is (x), which equation is correct?
Explanation opens after your attempt
Correct Answer
A. \(2x^2+2x-144=0\)
Concept
The integers are (x) and (x+1), so (x-2+(x+1)2=145). Simplifying gives \(2x^2+2x-144=0\).
Why this answer is correct
The correct answer is A. \(2x^2+2x-144=0\). The integers are (x) and (x+1), so (x-2+(x+1)2=145). Simplifying gives \(2x^2+2x-144=0\).
Exam Tip
पूर्णांक (x) और (x+1) होंगे, इसलिए (x-2+(x+1)2=145)। सरल करने पर \(2x^2+2x-144=0\) मिलता है।
