Step by step solution :

Step 1 :

Equation in ~ the finish of step 1 : 7x2 - 3x = 0

Step 2 :

Step 3 :

Pulling out prefer terms :3.1 pull out favor factors:7x2 - 3x=x•(7x - 3)

Equation at the end of step 3 :

x • (7x - 3) = 0

Step 4 :

Theory - roots of a product :4.1 A product of numerous terms amounts to zero.When a product of 2 or an ext terms amounts to zero, climate at the very least one of the terms should be zero.We shall currently solve every term = 0 separatelyIn other words, we space going to fix as numerous equations as there space terms in the productAny equipment of term = 0 solves product = 0 as well.

Solving a solitary Variable Equation:4.2Solve:x = 0 solution is x = 0

Solving a single Variable Equation:4.3Solve:7x-3 = 0Add 3 come both sides of the equation:7x = 3 division both sides of the equation by 7:x = 3/7 = 0.429

Two services were discovered :

x = 3/7 = 0.429x = 0
