$\left(x+1\right)\left(x-2\right)\left(4+x\right)=0$
Learn how to solve problems step by step online. Find the roots of (x+1)(x-2)(x+3+1)=0. Add the values 3 and 1. Break the equation in 3 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.
