Medium Mathematics Quadratic Equations Class 10 Level 30

समीकरण \(12-7x+x^2=0\) को \(ax^2+bx+c=0\) के रूप में लिखने पर (b) का मान क्या होगा?

When \(12-7x+x^2=0\) is written as \(ax^2+bx+c=0\), what is the value of (b)?

Explanation opens after your attempt
Correct Answer

B. (-7)

Step 1

Concept

In proper order, the equation is \(x^2-7x+12=0\). So the coefficient of (x) is (b=-7).

Step 2

Why this answer is correct

The correct answer is B. (-7). In proper order, the equation is \(x^2-7x+12=0\). So the coefficient of (x) is (b=-7).

Step 3

Exam Tip

सही क्रम में समीकरण \(x^2-7x+12=0\) है। इसलिए (x) का गुणांक (b=-7) है।
