12x 2 - 4x=0, x= kindly guide me
Answers
Answer:
24x - 4x = 0
20x =0
x=0/20
x=0
Answer:
x = 1/3 = 0.333
x = 0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(22•3x2) - 4x = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
12x2 - 4x = 4x • (3x - 1)
Equation at the end of step 3 :
4x • (3x - 1) = 0
Step 4 :
Theory - Roots of a product :
4.1 A product 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 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :
4.2 Solve : 4x = 0
Divide both sides of the equation by 4:
x = 0
Solving a Single Variable Equation :
4.3 Solve : 3x-1 = 0
Add 1 to both sides of the equation :
3x = 1
Divide both sides of the equation by 3:
x = 1/3 = 0.333
Two solutions were found :
x = 1/3 = 0.333
x = 0
