The correct Answer is:
To solve the quadratic equation given by \[ \frac{4x-3}{2x+1} - 10\left(\frac{2x+1}{4x-3}\right) = 3 \] we will follow these steps: ### Step 1: Set up the equation We start with the equation: \[ \frac{4x-3}{2x+1} - 10\left(\frac{2x+1}{4x-3}\right) = 3 \] ### Step 2: Let \( y = \frac{4x-3}{2x+1} \) We can simplify our equation by substituting \( y \): \[ y - 10\left(\frac{1}{y}\right) = 3 \] ### Step 3: Multiply through by \( y \) To eliminate the fraction, we multiply both sides by \( y \): \[ y^2 - 10 = 3y \] ### Step 4: Rearrange the equation Rearranging gives us a standard quadratic form: \[ y^2 - 3y - 10 = 0 \] ### Step 5: Factor the quadratic equation Now we need to factor \( y^2 - 3y - 10 \): \[ (y - 5)(y + 2) = 0 \] ### Step 6: Solve for \( y \) Setting each factor to zero gives us: 1. \( y - 5 = 0 \) → \( y = 5 \) 2. \( y + 2 = 0 \) → \( y = -2 \) ### Step 7: Substitute back for \( x \) Recall that \( y = \frac{4x-3}{2x+1} \). We will substitute back to find \( x \). #### For \( y = 5 \): \[ \frac{4x-3}{2x+1} = 5 \] Cross-multiplying gives: \[ 4x - 3 = 5(2x + 1) \] Expanding and rearranging: \[ 4x - 3 = 10x + 5 \] \[ 4x - 10x = 5 + 3 \] \[ -6x = 8 \] \[ x = -\frac{4}{3} \] #### For \( y = -2 \): \[ \frac{4x-3}{2x+1} = -2 \] Cross-multiplying gives: \[ 4x - 3 = -2(2x + 1) \] Expanding and rearranging: \[ 4x - 3 = -4x - 2 \] \[ 4x + 4x = -2 + 3 \] \[ 8x = 1 \] \[ x = \frac{1}{8} \] ### Final Solutions The solutions to the quadratic equation are: \[ x = -\frac{4}{3} \quad \text{and} \quad x = \frac{1}{8} \]
