Chapter 2: Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23
यदि (p(x)=x-3-12x-2+35x) है, तो ग्राफ के शून्यकों का समूह कौन सा है?
If (p(x)=x-3-12x-2+35x), what is the set of zeroes of the graph?
Explanation opens after your attempt
Correct Answer
A. (0,5,7)
Step 1
Concept
(x-3-12x-2+35x=x(x-5)(x-7)), so the zeroes are (0), (5), (7). Tip: first take (x) as the common factor.
Step 2
Why this answer is correct
The correct answer is A. (0,5,7). (x-3-12x-2+35x=x(x-5)(x-7)), so the zeroes are (0), (5), (7). Tip: first take (x) as the common factor.
Step 3
Exam Tip
(x-3-12x-2+35x=x(x-5)(x-7)) है, इसलिए शून्यक (0), (5), (7) हैं। टिप: पहले (x) सामान्य गुणनखंड निकालें।

If (p(x)=x-3-7x-2+10x), what is the mean of the zeroes of the graph?
Explanation opens after your attempt
Correct Answer
A. \(\frac{7}{3}\)
Step 1
Concept
(p(x)=x(x-5)(x-2)), so the zeroes are (0), (2), (5), and the mean is \(\frac{7}{3}\). Tip: factor first.
