Question

Find a cubic function with the given zeros. Square root of two., - Square root of two., -2 A. f(x) = x^3 + 2x^2 - 2x + 4 B. f(x) = x^3 + 2x^2 + 2x - 4 C. f(x) = x^3 - 2x^2 - 2x - 4 D. f(x) = x^3 + 2x^2 - 2x - 4

Answer 1

Hello,

Answer D


`(x- √(2) )*(x+ √(2) )*(x+2)\\\\ =(x^2-2)(x+2)\\\\ =x^3+2x^2-2x-4\\\\`
