Question

find the zeroes of the polynomial of each of the following polynomial ,and verify the relationship between the zeroes of the coefficient. (1 ) x^3-1. (2) 2x^2-x^3 class 10​

Answer 1

Answer:

P(x) => 3x² - 2x - 1

=> 3x² - 2x - 1

=> 3x² - 3x + x - 1

=> 3x(x - 1) + 1(x - 1)

=> (3x + 1) (x - 1)

=> x = -1/3 Or x = 1

Hence, x = -1/3 Or x = 1

Verification:-

P(x) => 3x² - 2x - 1

a = 3

b = -2

c = -1

Let α and β are the zeroes of the given polynomial.

α = -1/3

β = 1

Sum of zeroes = -b/a

=> -1/3 + 1 = -(-2)/3

=> -1 + 3 / 3 = 2/3

=> 2/3 = 2/3

Product of zeroes = c/a

=> -1/3 × 1 = -1/3

=> -1/3 = -1/3

Verify
