Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24
यदि ग्राफ (x)-अक्ष को (-7) और (-2) पर काटता है तो (p(x)=0) के हल कौन से होंगे?
If a graph cuts the (x)-axis at (-7) and (-2), what are the solutions of (p(x)=0)?
#equation-solution
#graphical-zeroes
#negative-zeroes
A (-7) और (-2) / (-7) and (-2)
B (7) और (2) / (7) and (2)
C (-7) और (2) / (-7) and (2)
D कोई नहीं / None

Correct Answer
A. (-7) और (-2) / (-7) and (-2)
Step 1
Concept
The solutions of (p(x)=0) are where the graph meets the (x)-axis. So both given (x)-values are solutions.
Step 2
Why this answer is correct
The correct answer is A. (-7) और (-2) / (-7) and (-2). The solutions of (p(x)=0) are where the graph meets the (x)-axis. So both given (x)-values are solutions.
Step 3
Exam Tip
(p(x)=0) के हल वही हैं जहाँ ग्राफ (x)-अक्ष से मिलता है। इसलिए दिए गए दोनों (x)-मान हल हैं।

यदि (p(x)=2x+6), तो ग्राफ का (x)-अक्ष से कटाव किस (x)-मान पर होगा?
If (p(x)=2x+6), at which (x)-value will the graph cut the (x)-axis?

A (-3)
B (3)
C (6)
D (-6)

Step 1
Concept
On the (x)-axis, (p(x)=0), so (2x+6=0) gives (x=-3). This is the graphical zero.
Step 2
Why this answer is correct
The correct answer is A. (-3). On the (x)-axis, (p(x)=0), so (2x+6=0) gives (x=-3). This is the graphical zero.
Step 3
Exam Tip
(x)-अक्ष पर (p(x)=0), इसलिए (2x+6=0) से (x=-3)। यही ग्राफीय शून्यक है।
