Answer:

Answer D

Step-by-step explanation:

x^2 - 2 can be rewritten as ( x-sqrt(2)(x+sqrt(2) ). Thus, in factored form, we have f(x) = (x-3)(x-sqrt(2)(x+sqrt(2). Set this equal to zero and solve for the three roots:

x-3=0 yields x = 3.

x-sqrt(2) = 0 yields x = sqrt(2), and

x+sqrt(2) = 0 yields x = -sqrt(2).

This matches Answer D.

Solve The Two Equations for x.

natulia [17]

Answer:

x = 7, x = 5

Step-by-step explanation:

$\frac{3x+3}{8}$ = 2x - 11 ( multiply both sides by 8 to clear the fraction )

3x + 3 = 16x - 88 ( subtract 3x from both sides )

3 = 13x - 88 ( add 88 to both sides )

91 = 13x ( divide both sides by 13 )

7 = x

--------------------------------------------------------------

$\frac{4x-6}{7}$ = 2 ( multiply both sides by 7 )

4x - 6 = 14 ( add 6 to both sides )

4x = 20 ( divide both sides by 4 )

x = 5
