Question

find the zeros of the polynomial and verify the relationship between the coefficients and the zeros of 2 x square - 9​

Answer 1

Answer:

2x²- 9 = 0

2x² - (√9)² = 0

(2x - √9) (2x +√9) = 0

2x - √9 = 0. 2x +√ 9 =0

2x - 3 = 0 2x + 3 =0

2x = 3. 2x = -3

x = 3/2 x= -3/2

Sum of the zeroes = - b/a

alpa + beta = -0/2

3/2 - 3/2 = 0

0 =. 0

Product of the zeroes = c/a

alpa(beta) =. -9/2

3/2(-3/2) = -9/2

-9/2. = -9/2
