Math Problem Statement

3 over 2=11over2x x-2 over x

Solution

Let's break down and solve the equation step by step.

The equation you provided is:

32=112x×x2x\frac{3}{2} = \frac{11}{2x} \times \frac{x-2}{x}

Step 1: Simplify the right-hand side.

The right-hand side is a product of two fractions:

112x×x2x=11(x2)2x2\frac{11}{2x} \times \frac{x-2}{x} = \frac{11(x-2)}{2x^2}

So, the equation becomes:

32=11(x2)2x2\frac{3}{2} = \frac{11(x-2)}{2x^2}

Step 2: Eliminate the denominators.

Multiply both sides of the equation by 2x22x^2 to remove the denominators:

32x2=11(x2)23 \cdot 2x^2 = 11(x - 2) \cdot 2

This simplifies to:

6x2=22(x2)6x^2 = 22(x - 2)

Step 3: Expand both sides.

Expand the right-hand side:

6x2=22x446x^2 = 22x - 44

Step 4: Rearrange the equation.

Move all terms to one side of the equation:

6x222x+44=06x^2 - 22x + 44 = 0

Step 5: Simplify the equation.

Divide the entire equation by 2 to make it simpler:

3x211x+22=03x^2 - 11x + 22 = 0

Step 6: Solve the quadratic equation.

Now we need to solve the quadratic equation 3x211x+22=03x^2 - 11x + 22 = 0. We can use the quadratic formula:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Here, a=3a = 3, b=11b = -11, and c=22c = 22. Plug these values into the formula:

x=(11)±(11)24(3)(22)2(3)x = \frac{-(-11) \pm \sqrt{(-11)^2 - 4(3)(22)}}{2(3)} x=11±1212646x = \frac{11 \pm \sqrt{121 - 264}}{6} x=11±1436x = \frac{11 \pm \sqrt{-143}}{6}

Since 143\sqrt{-143} is imaginary, the solutions are complex numbers:

x=11±i1436x = \frac{11 \pm i\sqrt{143}}{6}

Final Answer:

The solutions to the equation are complex:

x=11+i1436orx=11i1436x = \frac{11 + i\sqrt{143}}{6} \quad \text{or} \quad x = \frac{11 - i\sqrt{143}}{6}
