Answer 2

Answer:

The solutions for x are √2 and -√2.

Step-by-step explanation:

using (a^2-b^2) = (a+b)(a-b),

(x^2-2) can be written as ( x-√2 )( x+√2)

equating ( x-√2 ) to 0,

x-√2=0, therefore x = √2

equating ( x+√2) to 0,

x+√2=0, therefore x = - √2

∴ α = √2

β = - √2

a = 1, b = 0, c = -2

so we get: α+β= -b/a, α*β=c/a after substituting the values
