## Step 1 :

Equation at the over of step 1 : x • (x - 1) • (x + 3) = 0

## Step 2 :

Equation at the kết thúc of step 2 : x • (x - 1) • (x + 3) = 0

## Step 3 :

Theory - Roots of a hàng hóa :3.1 A hàng hóa of several terms equals zero.When a product of two or more terms equals zero, then at least one of the terms must be zero.We shall now solve each term = 0 separatelyIn other words, we are going to lớn solve as many equations as there are terms in the productAny solution of term = 0 solves sản phẩm = 0 as well.

Solving a Single Variable Equation:3.2Solve:x = 0 Solution is x = 0

Solving a Single Variable Equation:3.3Solve:x-1 = 0Add 1 lớn both sides of the equation:x = 1

Solving a Single Variable Equation:3.4Solve:x+3 = 0Subtract 3 from both sides of the equation:x = -3

## Three solutions were found :

x = -3x = 1x = 0
