## Step-by-step Solution

Problem to solve:

$\left(x+1\right)\left(x-2\right)=0$

Specify the solving method

1

Break the equation in factors and set each equal to zero, to obtain

$x-2=0,\:x+1=0$
2

Solve the equation ($1$)

$x-2=0$
3

We need to isolate the dependent variable $x$, we can do that by subtracting $-2$ from both sides of the equation

$x=2$
4

Solve the equation ($2$)

$x+1=0$
5

We need to isolate the dependent variable $x$, we can do that by subtracting $1$ from both sides of the equation

$x=-1$
6

Combining all solutions, the $2$ solutions of the equation are

$x=2,\:x=-1$

$x=2,\:x=-1$
