Answer

The solutions are \( v = 6 \) and \( v = -\frac{4}{5} \).

Solution

**Step 1.** Write the equation in standard form: \[ 5v^2 - 26v = 24 \quad \Rightarrow \quad 5v^2 - 26v - 24 = 0 \] **Step 2.** Identify the coefficients: \[ a = 5, \quad b = -26, \quad c = -24 \] **Step 3.** Use the quadratic formula: \[ v = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] **Step 4.** Compute the discriminant: \[ b^2 - 4ac = (-26)^2 - 4(5)(-24) = 676 + 480 = 1156 \] \[ \sqrt{1156} = 34 \] **Step 5.** Substitute the values into the quadratic formula: \[ v = \frac{-(-26) \pm 34}{2 \cdot 5} = \frac{26 \pm 34}{10} \] **Step 6.** Find the two solutions: \[ v = \frac{26 + 34}{10} = \frac{60}{10} = 6 \] \[ v = \frac{26 - 34}{10} = \frac{-8}{10} = -\frac{4}{5} \] **Step 7.** Write the solution set: \[ \{6, -\frac{4}{5}\} \]

The Deep Dive

To solve the equation \( 5v^{2} - 26v - 24 = 0 \), we can use the quadratic formula, which is given by \( v = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a} \). Here, \( a = 5 \), \( b = -26 \), and \( c = -24 \). First, we calculate the discriminant: \[ b^{2} - 4ac = (-26)^{2} - 4(5)(-24) = 676 + 480 = 1156. \] Now, we can apply the quadratic formula: \[ v = \frac{-(-26) \pm \sqrt{1156}}{2 \times 5} = \frac{26 \pm 34}{10}. \] Calculating both possible values: 1. \( v = \frac{60}{10} = 6 \). 2. \( v = \frac{-8}{10} = -\frac{4}{5} \). Thus, the solution set is \( \{ 6, -\frac{4}{5} \} \).
