Correct Answer

A. ऊपरAbove

Step 1

Concept

In this interval the factor signs are (+), (+), (-), and the outside negative makes the value positive. Tip: apply the outside sign at the end.

Step 2

Why this answer is correct

The correct answer is A. ऊपर / Above. In this interval the factor signs are (+), (+), (-), and the outside negative makes the value positive. Tip: apply the outside sign at the end.

Step 3

Exam Tip

इस अंतराल में कारकों के चिह्न (+), (+), (-) हैं और बाहर का ऋण चिन्ह मान को धनात्मक बनाता है। टिप: बाहरी चिन्ह को अंत में लगाएं।

Question 3/4 Hard Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि (p(x)=-(x+5)(x-1)) है तो (-5<x<1) में ग्राफ (x)-अक्ष के किस ओर होगा?

If (p(x)=-(x+5)(x-1)), on which side of the (x)-axis will the graph lie for (-5<x<1)?

Explanation opens after your attempt
Correct Answer

A. ऊपरAbove

Step 1

Concept

In this interval the first factor is positive and the second is negative, so the outside negative makes the value positive. Tip: check each factor's sign separately.

Step 2

Why this answer is correct

The correct answer is A. ऊपर / Above. In this interval the first factor is positive and the second is negative, so the outside negative makes the value positive. Tip: check each factor's sign separately.

Step 3

Exam Tip

इस अंतराल में पहला कारक धनात्मक और दूसरा ऋणात्मक है इसलिए बाहर का ऋण चिन्ह मान को धनात्मक बनाता है। टिप: हर कारक का चिह्न अलग जांचें।
