The correct Answer is:
To solve the equation \[ \frac{x + 3}{x - 2} - \frac{1 - x}{x} = \frac{17}{4}, \quad x \neq 0, 2 \] we will follow these steps: ### Step 1: Find a common denominator The common denominator for the left-hand side is \(x(x - 2)\). We rewrite the equation: \[ \frac{(x + 3)x - (1 - x)(x - 2)}{x(x - 2)} = \frac{17}{4} \] ### Step 2: Expand the numerators Now we expand the numerators: 1. For \((x + 3)x\): \[ x^2 + 3x \] 2. For \(-(1 - x)(x - 2)\): \[ -(1 - x)(x - 2) = -(x - 2 - x^2 + 2x) = -(-x^2 + 3x - 2) = x^2 - 3x + 2 \] Combining these, we have: \[ x^2 + 3x + x^2 - 3x + 2 = 2x^2 + 2 \] ### Step 3: Set up the equation Now substituting back into the equation gives: \[ \frac{2x^2 + 2}{x(x - 2)} = \frac{17}{4} \] ### Step 4: Cross-multiply Cross-multiplying yields: \[ 4(2x^2 + 2) = 17x(x - 2) \] ### Step 5: Expand both sides Expanding both sides: 1. Left side: \[ 8x^2 + 8 \] 2. Right side: \[ 17x^2 - 34x \] So we have: \[ 8x^2 + 8 = 17x^2 - 34x \] ### Step 6: Rearrange the equation Rearranging gives: \[ 0 = 17x^2 - 8x^2 - 34x - 8 \] This simplifies to: \[ 9x^2 - 34x - 8 = 0 \] ### Step 7: Factor the quadratic equation To factor \(9x^2 - 34x - 8\), we look for two numbers that multiply to \(9 \times -8 = -72\) and add to \(-34\). The numbers are \(-36\) and \(2\). Rewriting the equation: \[ 9x^2 - 36x + 2x - 8 = 0 \] Grouping gives: \[ (9x^2 - 36x) + (2x - 8) = 0 \] Factoring out common terms: \[ 9x(x - 4) + 2(x - 4) = 0 \] Factoring out \((x - 4)\): \[ (x - 4)(9x + 2) = 0 \] ### Step 8: Solve for \(x\) Setting each factor to zero gives: 1. \(x - 4 = 0 \Rightarrow x = 4\) 2. \(9x + 2 = 0 \Rightarrow x = -\frac{2}{9}\) ### Final Solution Thus, the solutions are: \[ x = 4 \quad \text{and} \quad x = -\frac{2}{9} \]
