The correct Answer is:
To solve the given equations step by step, we will first tackle each equation separately. ### Step 1: Solve Equation I The first equation is: \[ 4x^2 - 14x + 6 = 0 \] To solve this quadratic equation, we can factor it. We will look for two numbers that multiply to \(4 \times 6 = 24\) and add up to \(-14\). We can rewrite \(-14x\) as \(-12x - 2x\): \[ 4x^2 - 12x - 2x + 6 = 0 \] Now, we can group the terms: \[ (4x^2 - 12x) + (-2x + 6) = 0 \] Factoring out the common factors: \[ 4x(x - 3) - 2(x - 3) = 0 \] Now, we can factor out \((x - 3)\): \[ (x - 3)(4x - 2) = 0 \] Setting each factor to zero gives us: 1. \( x - 3 = 0 \) → \( x = 3 \) 2. \( 4x - 2 = 0 \) → \( 4x = 2 \) → \( x = \frac{1}{2} \) So, the solutions for \(x\) are: \[ x = 3 \quad \text{and} \quad x = \frac{1}{2} \] ### Step 2: Solve Equation II The second equation is: \[ 4y^2 - 8y + 3 = 0 \] Again, we will factor this quadratic equation. We need two numbers that multiply to \(4 \times 3 = 12\) and add up to \(-8\). We can rewrite \(-8y\) as \(-6y - 2y\): \[ 4y^2 - 6y - 2y + 3 = 0 \] Now, we can group the terms: \[ (4y^2 - 6y) + (-2y + 3) = 0 \] Factoring out the common factors: \[ 2y(2y - 3) - 1(2y - 3) = 0 \] Now, we can factor out \((2y - 3)\): \[ (2y - 3)(2y - 1) = 0 \] Setting each factor to zero gives us: 1. \( 2y - 3 = 0 \) → \( 2y = 3 \) → \( y = \frac{3}{2} \) 2. \( 2y - 1 = 0 \) → \( 2y = 1 \) → \( y = \frac{1}{2} \) So, the solutions for \(y\) are: \[ y = \frac{3}{2} \quad \text{and} \quad y = \frac{1}{2} \] ### Step 3: Compare the Values of x and y Now we have the values: - For \(x\): \(3\) and \(\frac{1}{2}\) - For \(y\): \(\frac{3}{2}\) and \(\frac{1}{2}\) We need to compare these values: - \(3 > \frac{3}{2}\) - \(3 > \frac{1}{2}\) - \(\frac{1}{2} < \frac{3}{2}\) From this comparison, we can conclude: \[ x \text{ can be greater than or equal to } y \] ### Final Answer The correct relation is: \[ x \geq y \]
