Question

Find the value of x - if x^3-7x² - x = 0a) 17 (b) 71 c) 7d) 1​

Answer 1

Answer:

x = 0

Step-by-step explanation:

$x^3-7x^2-x =0$

Take out common factor

$x(x^2-7x-1) = 0$

The factor inside the parenthesis cannot be factored

Since there is a common factor that we pulled out of the original equation,

set that x equal to zero and solve

$x = 0$ : Therefore x = 0
