1

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

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

Learn how to solve one-variable linear equations problems step by step online.

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

Learn how to solve one-variable linear equations problems step by step online. Solve the equation (x+2)(x-1)=0. Break the equation in factors and set each equal to zero, to obtain. Solve the equation (1). We need to isolate the dependent variable x, we can do that by simultaneously subtracting -1 from both sides of the equation. Canceling terms on both sides.

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