Solve for x 4x-36/x=0

Problem

4*x−36/x=0

Solution

1. Identify the domain of the equation by noting that x cannot be zero because division by zero is undefined.

2. Multiply every term in the equation by x to eliminate the fraction.

x*(4*x)−x(36/x)=x(0)

3. Simplify the resulting equation into a quadratic form.

4*x2−36=0

4. Isolate the x2 term by adding 36 to both sides and then dividing by 4

4*x2=36

x2=9

5. Solve for x by taking the square root of both sides, remembering to include both the positive and negative roots.

x=±√(,9)

x=3,x=−3

Final Answer

x=±3
