Question

the sum of the zeros of polynomial एक्स 2 माइनस टू एक्स माइनस 8 फुल एचडी ​

Answer 1

Answer:

x²- 4

Step-by-step explanation:

$\alpha = 2 \: and \: \beta = - 2 \\ sum \: of \: zeroes \: = \alpha + \beta \\ = 2 + ( - 2) = 0 \\ product \: of \: zeroes = \alpha \beta \\ = 2 \times ( - 2) \\ = - 4 \\ quadratic \: formula \: = {x }^{2} + (sum \: of \: zeroes)x + product \: of \: zeroes \\ = {x }^{2} + (0)x + ( - 4) \\ {x }^{2} - 4$
