Step by action solution :

Step 1 :

Equation in ~ the finish of action 1 : 2x2 - 8x = 0

Step 2 :

Step 3 :

Pulling out favor terms :3.1 pull out prefer factors:2x2 - 8x=2x•(x - 4)

Equation at the finish of step 3 :

2x • (x - 4) = 0

Step 4 :

Theory - root of a product :4.1 A product of number of terms equals zero.When a product of 2 or more terms equates to zero, then at the very least one that the terms should be zero.We shall currently solve every term = 0 separatelyIn various other words, we space going to solve as countless equations together there room terms in the productAny equipment of ax = 0 solves product = 0 together well.

Solving a solitary Variable Equation:4.2Solve:2x = 0Divide both political parties of the equation through 2:x = 0

Solving a solitary Variable Equation:4.3Solve:x-4 = 0Add 4 come both political parties of the equation:x = 4

Two solutions were discovered :

x = 4x = 0
