The correct Answer is:
To solve the quadratic equation \(2x^2 - 5x + 3 = 0\), we can use the method of factoring. Here are the steps to solve the equation: ### Step 1: Identify the coefficients In the equation \(2x^2 - 5x + 3 = 0\), we identify the coefficients: - \(a = 2\) - \(b = -5\) - \(c = 3\) ### Step 2: Multiply \(a\) and \(c\) Next, we multiply \(a\) and \(c\): \[ ac = 2 \times 3 = 6 \] ### Step 3: Find two numbers that multiply to \(ac\) and add to \(b\) We need to find two numbers that multiply to \(6\) (the value of \(ac\)) and add to \(-5\) (the value of \(b\)). The numbers that satisfy this condition are \(-2\) and \(-3\) because: \[ -2 \times -3 = 6 \quad \text{and} \quad -2 + -3 = -5 \] ### Step 4: Rewrite the middle term Now we rewrite the equation by splitting the middle term using the two numbers found: \[ 2x^2 - 2x - 3x + 3 = 0 \] ### Step 5: Group the terms Next, we group the terms: \[ (2x^2 - 2x) + (-3x + 3) = 0 \] ### Step 6: Factor by grouping Now we factor out the common terms in each group: \[ 2x(x - 1) - 3(x - 1) = 0 \] ### Step 7: Factor out the common binomial Now we can factor out the common binomial \((x - 1)\): \[ (2x - 3)(x - 1) = 0 \] ### Step 8: Set each factor to zero Now we set each factor equal to zero: 1. \(2x - 3 = 0\) 2. \(x - 1 = 0\) ### Step 9: Solve for \(x\) Now we solve each equation: 1. From \(2x - 3 = 0\): \[ 2x = 3 \implies x = \frac{3}{2} \] 2. From \(x - 1 = 0\): \[ x = 1 \] ### Step 10: Write the solutions Thus, the solutions to the equation \(2x^2 - 5x + 3 = 0\) are: \[ x = \frac{3}{2} \quad \text{and} \quad x = 1 \] ---
