Correct Answer

A. \(x^2-9x-36=0\)

Step 1

Concept

The statement gives \(x^2-9x=36\). Bringing all terms to one side gives \(x^2-9x-36=0\).

Step 2

Why this answer is correct

The correct answer is A. \(x^2-9x-36=0\). The statement gives \(x^2-9x=36\). Bringing all terms to one side gives \(x^2-9x-36=0\).

Step 3

Exam Tip

वाक्य से \(x^2-9x=36\) बनता है। सभी पद एक ओर लाने पर \(x^2-9x-36=0\) मिलता है।
