Question

C^4 - c^3 - 2c^2 - 2c = 0Help please!!

Answer 1

Problem

`C^4-C^3-2C^2\text{ + 2C = 0}`

Step 1: Factor C out of the equation, we get:

`C(C^3-C^2\text{ - 2C + 2) = 0}`

Step 2: factor the expression in the bracket

`C^3-C^2\text{ - 2C + 2 = 0}`

From the expression above, find the first zero. C = 1 is a zero of the expression because C - 1 is a factor.

Therefore
