Class 10 Math Chapter 2 Question Answer NCERT

Exercise 2.1 – Important Solutions

Q1. Find the zero of the polynomial p(x) = 2x + 3

Solution:
2x + 3 = 0
⇒ x = −3/2

Answer: Zero = −3/2

অসমীয়া:
শূন্য = −3/2

---

Q2. Find the zero of p(x) = x² − 4

x² − 4 = 0
⇒ (x − 2)(x + 2) = 0

Zeros: x = 2, −2

অসমীয়া:
শূন্যসমূহ = 2 আৰু −2

---

🟢 4. Relationship between Zeros and Coefficients

For quadratic polynomial:$$ax^2 + bx + c$$ax2+bx+c

English:

• Sum of zeros = $-\frac{b}{a}$−ab​
• Product of zeros = $\frac{c}{a}$ac​

Assamese:

• শূন্যসমূহৰ যোগফল = $-\frac{b}{a}$−ab​
• শূন্যসমূহৰ গুণফল = $\frac{c}{a}$ac​
