Q:
# hat are the solutions of the equation x4 β 5x2 β 14 = 0? Use factoring to solve.

Accepted Solution

A:

-7 and 2 are factors of -14, and they make a sum of -5, therefore:

(x^2-7)(x^2+2)=0

x^=7 or x^=-2

x=β7 or-β7, x=β2i or x=-β2i

(x^2-7)(x^2+2)=0

x^=7 or x^=-2

x=β7 or-β7, x=β2i or x=-β2i
