दो क्रमागत धनात्मक पूर्णांकों का गुणनफल (56) है। सही द्विघात समीकरण कौन-सा है?
The product of two consecutive positive integers is (56). Which quadratic equation is correct?
Explanation opens after your attempt
Correct Answer
A. \(x^2+x-56=0\)
Concept
The numbers are (x) and (x+1), so (x(x+1)=56). This gives \(x^2+x-56=0\).
Why this answer is correct
The correct answer is A. \(x^2+x-56=0\). The numbers are (x) and (x+1), so (x(x+1)=56). This gives \(x^2+x-56=0\).
Exam Tip
संख्याएँ (x) और (x+1) होंगी, इसलिए (x(x+1)=56)। इससे \(x^2+x-56=0\) मिलता है।
