The correct Answer is:
To solve the quadratic equation \( \sqrt{3} x^2 - 2\sqrt{2} x - 2\sqrt{3} = 0 \), we can follow these steps: ### Step 1: Identify the coefficients The equation is in the standard form \( ax^2 + bx + c = 0 \), where: - \( a = \sqrt{3} \) - \( b = -2\sqrt{2} \) - \( c = -2\sqrt{3} \) ### Step 2: Calculate the product \( ac \) We need to calculate \( ac \): \[ ac = \sqrt{3} \times (-2\sqrt{3}) = -6 \] ### Step 3: Find two numbers that multiply to \( ac \) and add to \( b \) We need to find two numbers that multiply to \( -6 \) and add to \( -2\sqrt{2} \). The numbers are \( -3\sqrt{2} \) and \( \sqrt{2} \) because: \[ -3\sqrt{2} \times \sqrt{2} = -6 \quad \text{and} \quad -3\sqrt{2} + \sqrt{2} = -2\sqrt{2} \] ### Step 4: Rewrite the middle term We can rewrite the equation by splitting the middle term: \[ \sqrt{3} x^2 - 3\sqrt{2} x + \sqrt{2} x - 2\sqrt{3} = 0 \] ### Step 5: Factor by grouping Now, we will group the terms: \[ (\sqrt{3} x^2 - 3\sqrt{2} x) + (\sqrt{2} x - 2\sqrt{3}) = 0 \] Factoring out common terms: \[ \sqrt{3} x (x - \sqrt{2}) + \sqrt{2} (x - \sqrt{3}) = 0 \] ### Step 6: Factor completely We can factor this as: \[ (\sqrt{3} x + \sqrt{2})(x - \sqrt{2}) = 0 \] ### Step 7: Set each factor to zero Now we set each factor to zero: 1. \( \sqrt{3} x + \sqrt{2} = 0 \) 2. \( x - \sqrt{2} = 0 \) ### Step 8: Solve for \( x \) From the first factor: \[ \sqrt{3} x = -\sqrt{2} \implies x = -\frac{\sqrt{2}}{\sqrt{3}} = -\frac{\sqrt{6}}{3} \] From the second factor: \[ x = \sqrt{2} \] ### Final Solutions Thus, the solutions to the equation are: \[ x = -\frac{\sqrt{6}}{3} \quad \text{and} \quad x = \sqrt{2} \]
