The correct Answer is:
To solve the given equations step by step, we will start with each equation separately. ### Step 1: Solve the first equation \(5x^2 - 13x + 6 = 0\) 1. **Identify the coefficients**: - \(a = 5\) - \(b = -13\) - \(c = 6\) 2. **Factor the quadratic equation**: We need to find two numbers that multiply to \(a \cdot c = 5 \cdot 6 = 30\) and add up to \(b = -13\). - The numbers are \(-10\) and \(-3\) because \(-10 \cdot -3 = 30\) and \(-10 + -3 = -13\). 3. **Rewrite the equation**: \[ 5x^2 - 10x - 3x + 6 = 0 \] 4. **Group the terms**: \[ (5x^2 - 10x) + (-3x + 6) = 0 \] 5. **Factor by grouping**: \[ 5x(x - 2) - 3(x - 2) = 0 \] \[ (5x - 3)(x - 2) = 0 \] 6. **Set each factor to zero**: - \(5x - 3 = 0 \Rightarrow x = \frac{3}{5}\) - \(x - 2 = 0 \Rightarrow x = 2\) ### Step 2: Solve the second equation \(2y^2 - 7y + 6 = 0\) 1. **Identify the coefficients**: - \(a = 2\) - \(b = -7\) - \(c = 6\) 2. **Factor the quadratic equation**: We need two numbers that multiply to \(a \cdot c = 2 \cdot 6 = 12\) and add up to \(b = -7\). - The numbers are \(-3\) and \(-4\) because \(-3 \cdot -4 = 12\) and \(-3 + -4 = -7\). 3. **Rewrite the equation**: \[ 2y^2 - 3y - 4y + 6 = 0 \] 4. **Group the terms**: \[ (2y^2 - 3y) + (-4y + 6) = 0 \] 5. **Factor by grouping**: \[ y(2y - 3) - 2(2y - 3) = 0 \] \[ (2y - 3)(y - 2) = 0 \] 6. **Set each factor to zero**: - \(2y - 3 = 0 \Rightarrow y = \frac{3}{2}\) - \(y - 2 = 0 \Rightarrow y = 2\) ### Summary of Solutions: - For the first equation, \(x = \frac{3}{5}\) and \(x = 2\). - For the second equation, \(y = \frac{3}{2}\) and \(y = 2\).
