Math Problem Statement

What about write each quadratic equation in standard form 4/x + 10 = 4/x-1

Solution

To write the equation 4x+10=4x1\frac{4}{x} + 10 = \frac{4}{x-1} in standard form, follow these steps:

  1. Eliminate the fractions by multiplying every term by the least common denominator (LCD). In this case, the LCD is x(x1)x(x - 1):

    x(x1)(4x+10)=x(x1)(4x1)x(x - 1) \left(\frac{4}{x} + 10\right) = x(x - 1) \left(\frac{4}{x-1}\right)

  2. Distribute and simplify each side:

    On the left side: (x1)4+10x(x1)(x - 1) \cdot 4 + 10 \cdot x(x - 1)

    On the right side: 4x4 \cdot x

    So, you get: 4x4+10x210x=4x4x - 4 + 10x^2 - 10x = 4x

  3. Simplify and move all terms to one side to set the equation to zero:

    Subtract 4x4x from both sides: 10x210x4=010x^2 - 10x - 4 = 0

  4. Simplify the coefficients if possible:

    Divide the entire equation by 2 to simplify it: 5x25x2=05x^2 - 5x - 2 = 0

The equation 5x25x2=05x^2 - 5x - 2 = 0 is now in standard form.

Would you like more details on any of these steps or have any other questions?

Here are five related questions:

  1. How do you find the roots of a quadratic equation?
  2. What does it mean for a quadratic equation to be in standard form?
  3. How can you complete the square for a quadratic equation?
  4. What are the applications of quadratic equations in real life?
  5. How do you determine the axis of symmetry for a quadratic equation?

Tip: Always simplify the coefficients if possible after arranging the equation in standard form to make solving easier.
