Question 5 Which of the following shows one of the factors of the expression below x 2x 8 O a Ob x 2 x 2 x8 x 8 Od class=

Respuesta :

Given data:

The given expression is x² + 2x - 8.

The factors of the given expression is,

[tex]\begin{gathered} x^2+2x-8=x^2+4x-2x-8 \\ =x(x+4)-2(x+4) \\ =(x-2)(x+4)_{} \end{gathered}[/tex]

Thus, one of the factor is (x-2), so option (b) is correct.
