Hard Mathematics Polynomials Class 10 Level 22

यदि किसी ग्राफ पर शून्यक (-2), (3), (7) हैं, तो (x)-अक्ष कटान बिंदुओं का सही समूह कौन सा है?

If a graph has zeroes (-2), (3), (7), which is the correct set of (x)-axis intersection points?

Explanation opens after your attempt
Correct Answer

B. ((-2,0)), ((3,0)), ((7,0))

Step 1

Concept

A zero (a) gives the intersection point ((a,0)). Tip: write the zero as the first coordinate.

Step 2

Why this answer is correct

The correct answer is B. ((-2,0)), ((3,0)), ((7,0)). A zero (a) gives the intersection point ((a,0)). Tip: write the zero as the first coordinate.

Step 3

Exam Tip

शून्यक (a) का कटान बिंदु ((a,0)) होता है। टिप: शून्यक को पहले निर्देशांक में लिखें।
