यदि (p(x)=x-2 -5) है, तो ग्राफ (y=p(x)) (x)-अक्ष को कहाँ काटेगा?
If (p(x)=x-2 -5), where will the graph (y=p(x)) cut the (x)-axis?
#graphical-meaning
#irrational-zeroes
#x-intercepts
A \(x=\pm\sqrt{5}\)
B \(x=\pm5\)
C (x=0)
D \(x=\sqrt{25}\)
Explanation opens after your attempt
Correct Answer
A. \(x=\pm\sqrt{5}\)
Step 1
Concept
On the (x)-axis, (p(x)=0), so \(x^2-5=0\) gives \(x=\pm\sqrt{5}\). The (x)-intercepts are the zeroes.
Step 2
Why this answer is correct
The correct answer is A. \(x=\pm\sqrt{5}\). On the (x)-axis, (p(x)=0), so \(x^2-5=0\) gives \(x=\pm\sqrt{5}\). The (x)-intercepts are the zeroes.
Step 3
Exam Tip
(x)-अक्ष पर (p(x)=0), इसलिए \(x^2-5=0\) से \(x=\pm\sqrt{5}\) है। ग्राफ में (x)-कट शून्यक होते हैं।

Step 2
Why this answer is correct
The correct answer is A. ((-2,0)) और ((4,0)) / ((-2,0)) and ((4,0)). (x-2 -2x-8=(x-4)(x+2)). So the graph meets the (x)-axis at (x=4) and (x=-2).
Step 3
Exam Tip
(x-2 -2x-8=(x-4)(x+2)) है। अतः (x=4) और (x=-2) पर ग्राफ (x)-अक्ष से मिलेगा।
