Linear equations with one unknownStep by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x^212*x-(135)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(22x212 • x) - 135 = 0Step 2 :
Trying to factor as a Difference of Cubes:
2.1 Factoring: 4x213-135
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0-b3 =
a3-b3
Check : 4 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Equation at the end of step 2 :
4x213 - 135 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : 4x213-135 = 0
Add 135 to both sides of the equation :
4x213 = 135
Divide both sides of the equation by 4:
x213 = 135/4 = 33.750
x = 213th root of (135/4)
The equation has one real solution
This solution is x = 213th root of (33.750) = 1.01666
One solution was found :
x = 213th root of (33.750) = 1.01666How did we do?
