Solve the following equation:
To solve this problem, we will follow these steps:
Step 1: Multiply both sides of the equation by the least common denominator, , to eliminate the fractions:
This simplifies to:
Step 2: Expand both sides:
Left Side:
Right Side:
Let's break down the left side:
Adding these gives:
Expand the right side:
Step 3: Set the equation:
Upon simplification:
-9 = -4.5x^2
Solving gives:
Step 4: Solving for x, or .
Only falls into the choice. Verify: .
Therefore, the solution to the problem is .
\( (4b-3)(4b-3) \)
Rewrite the above expression as an exponential summation expression:
Multiplying by the LCD eliminates all fractions at once! This converts the complex rational equation into a polynomial equation that's much easier to solve.
When expanding and , use the pattern (a-b)³ = a³ - 3a²b + 3ab² - b³. Take your time with the arithmetic - cubic expansions have many terms!
Check domain restrictions! The original equation is undefined when x = 2 or x = 1/2. Any solution that equals these values must be rejected as extraneous.
After expanding and simplifying both sides, many cubic terms cancel out, leaving a simpler quadratic equation. This is common in rational equations - the complexity often reduces significantly!
Yes! You could let and , but multiplying by the LCD is usually more straightforward for this type of problem.
