Determine where the real zeros of f(x) = x4 - 2x3 + x - 2 are located.

Digiron [165]

Step-by-step explanation:

Step 1: Factor by grouping

$x^4 - 2x^3 + x - 2$

$x^3(x - 2) + 1(x - 2)$

$(x^3 + 1)(x - 2)$

Step 2: Solve for x

$x^3 + 1 = 0$

$x^3 = -1$

$\sqrt[3]{x^3} = \sqrt[3]{-1}$

$x = -1$

$x - 2 = 0$

$x - 2 + 2= 0 + 2$

$x = 2$

Answer: $Option\ A, \ at\ -1 \ \& \ 2$
