Expert Mathematics Polynomials Class 10 Level 24

यदि बहुपद (p(x)=5(x+1)(x-2)(x-4)) है तो ग्राफ (x)-अक्ष को कितने अलग बिंदुओं पर काटेगा?

If (p(x)=5(x+1)(x-2)(x-4)), at how many distinct points will the graph cut the (x)-axis?

Explanation opens after your attempt
Correct Answer

A. तीनThree

Step 1

Concept

The factors give zeroes (-1), (2), and (4). Three distinct zeroes give three distinct (x)-intercepts.

Step 2

Why this answer is correct

The correct answer is A. तीन / Three. The factors give zeroes (-1), (2), and (4). Three distinct zeroes give three distinct (x)-intercepts.

Step 3

Exam Tip

गुणनखंडों से शून्यक (-1), (2), और (4) हैं। तीन अलग शून्यक तीन अलग (x)-प्रतिच्छेद देते हैं।
