Math Problem Statement

1/x + 6/x² =1

Solution

To solve the equation 1x+6x2=1\frac{1}{x} + \frac{6}{x^2} = 1, follow these steps:

Step 1: Multiply the entire equation by x2x^2 to eliminate the denominators.

x2(1x+6x2)=x2×1x^2 \left(\frac{1}{x} + \frac{6}{x^2}\right) = x^2 \times 1 This simplifies to: xx+6=x2x \cdot x + 6 = x^2

Step 2: Simplify the equation.

x+6=x2x + 6 = x^2

Step 3: Rearrange the equation to form a standard quadratic equation.

x2x6=0x^2 - x - 6 = 0

Step 4: Factor the quadratic equation.

We need to find two numbers that multiply to 6-6 and add to 1-1. These numbers are 3-3 and 22. So, we can factor the equation as: (x3)(x+2)=0(x - 3)(x + 2) = 0

Step 5: Solve for xx.

Set each factor equal to zero: x3=0orx+2=0x - 3 = 0 \quad \text{or} \quad x + 2 = 0 x=3orx=2x = 3 \quad \text{or} \quad x = -2

Final Answer:

The solutions are x=3x = 3 and x=2x = -2.
