The correct Answer is:
To solve the quadratic equation \( \sqrt{3}x^2 + 11x + 6\sqrt{3} = 0 \), we will follow these steps: ### Step 1: Identify the coefficients The given quadratic equation is in the standard form \( ax^2 + bx + c = 0 \). Here, - \( a = \sqrt{3} \) - \( b = 11 \) - \( c = 6\sqrt{3} \) ### Step 2: Calculate the product \( ac \) We need to find the product \( ac \): \[ ac = \sqrt{3} \times 6\sqrt{3} = 6 \times 3 = 18 \] ### Step 3: Find two numbers that multiply to \( ac \) and add to \( b \) We need to find two numbers that multiply to \( 18 \) and add up to \( 11 \). The numbers are \( 9 \) and \( 2 \) because: \[ 9 \times 2 = 18 \quad \text{and} \quad 9 + 2 = 11 \] ### Step 4: Rewrite the middle term Now, we can rewrite the equation by splitting the middle term \( 11x \) into \( 9x + 2x \): \[ \sqrt{3}x^2 + 9x + 2x + 6\sqrt{3} = 0 \] ### Step 5: Factor by grouping Group the terms: \[ (\sqrt{3}x^2 + 9x) + (2x + 6\sqrt{3}) = 0 \] Now, factor out the common terms from each group: \[ x(\sqrt{3}x + 9) + 2(\sqrt{3}x + 3) = 0 \] ### Step 6: Factor out the common binomial Now we can factor out \( \sqrt{3}x + 9 \): \[ (\sqrt{3}x + 9)(x + 2) = 0 \] ### Step 7: Set each factor to zero Now we set each factor to zero: 1. \( \sqrt{3}x + 9 = 0 \) 2. \( x + 2 = 0 \) ### Step 8: Solve for \( x \) For the first equation: \[ \sqrt{3}x + 9 = 0 \implies \sqrt{3}x = -9 \implies x = -\frac{9}{\sqrt{3}} = -3\sqrt{3} \] For the second equation: \[ x + 2 = 0 \implies x = -2 \] ### Final Solution The roots of the quadratic equation are: \[ x = -3\sqrt{3} \quad \text{and} \quad x = -2 \] ---

To solve the quadratic equation \( \sqrt{3}x^2 + 11x + 6\sqrt{3} = 0 \), we will follow these steps: ### Step 1: Identify the coefficients The given quadratic equation is in the standard form \( ax^2 + bx + c = 0 \). Here, - \( a = \sqrt{3} \) - \( b = 11 \) - \( c = 6\sqrt{3} \) ...
