किस स्थिति में द्विघात समीकरण बनेगा?
Which situation will form a quadratic equation?
Explanation opens after your attempt
B. संख्या और उसके (3) अधिक मान का गुणनफल (88) हैA number and (3) more than it have product (88)
Concept
Option (B) forms (x(x+3)=88), which is quadratic. When a variable is multiplied by a variable expression, an \(x^2\) term appears.
Why this answer is correct
The correct answer is B. संख्या और उसके (3) अधिक मान का गुणनफल (88) है / A number and (3) more than it have product (88). Option (B) forms (x(x+3)=88), which is quadratic. When a variable is multiplied by a variable expression, an \(x^2\) term appears.
Exam Tip
विकल्प (B) में (x(x+3)=88) बनता है, जो द्विघात है। गुणनफल में चर के साथ चर हो तो \(x^2\) पद आता है।
