1. Zero of a Polynomial Kya Hota Hai? 🤔
Simple language mein: Variable (x) ki wo value, jise put karne par poora polynomial Zero (0) ban jaye.
Imagine karo ek shor machane wala machine (Polynomial) hai. Hamein ek aisa button (Value of x) dhundhna hai, jise dabate hi machine shant ho jaye (Value 0 ho jaye).
Uss button ko hum Zero of the Polynomial kehte hain.
✔ Example:
Polynomial: p(x) = x - 2
Agar hum x = 2 put karein:
p(2) = 2 - 2 = 0
Example 1: Find zero of p(x) = 2x + 1
- Put
2x + 1 = 0 2x = -1x = -1/2
Check x = 0:
(0)² - 2(0) = 0 - 0 = 0 ✅ (Yes, it is a zero)
📝 Exercise Questions
Khud try karein! Neeche diye gaye questions solve karein.
Q1: Find the zero of p(x) = x - 5
Show Answer
Put x - 5 = 0
x = 5
Q2: Find the zero of q(x) = 3x + 4
Show Answer
Put 3x + 4 = 0
3x = -4
x = -4/3
Q3: Verify if x = -1 is a zero of p(x) = x + 1
Show Answer
Put x = -1 in p(x)
p(-1) = -1 + 1 = 0
Yes, it is a zero.
