Answer 2

Answer:

1. √2x2 - 3√3x + √6

+ anxn, where an ≠ 0, is called a polynomial in x of degree n.

1. ANSWER (C) 3, -1 We have, f(x) = x2 - 2x – 3 Now, put f(x) = 0 x2 - 2x – 3 = 0 x2 -3x + x – 3 = 0 x(x – 3) + 1(x – 3) = 0 (x + 1)(x – 3) = 0 x – 3 = 0 or x + 1 = 0 x = 3 or x = -1 So, the zeros of given polynomial are 3 and -1
