Explanation opens after your attempt
Correct Answer

A. (8)

Step 1

Concept

Here (a=3), (b=-2), (c=7), so (a+b+c=8). Always include the signs of coefficients.

Step 2

Why this answer is correct

The correct answer is A. (8). Here (a=3), (b=-2), (c=7), so (a+b+c=8). Always include the signs of coefficients.

Step 3

Exam Tip

यहाँ (a=3), (b=-2), (c=7), इसलिए (a+b+c=8) है। गुणांकों के चिन्ह हमेशा साथ लिखें।
