Algebra: Solving a Quadratic Equation

Problem: Solve \( 2x^2 - 5x + 3 = 0 \). Approach: Use the quadratic formula \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \). Calculate the discriminant: \[ \Delta = (-5)^2 - 4 \times 2 \times 3 = 25 - 24 = 1 \] Then, \[ x = \frac{5 \pm 1}{4} \] So, \[ x = \frac{6}{4} = 1.5 \quad \text{or} \quad x = \frac{4}{4} = 1 \] This reinforces solving standard algebraic equations.

Coordinate Geometry: Equation of a Circle

Problem: Find the equation of a circle with center at (2, -3) and radius 5. Approach: Use the standard form of a circle’s equation: \[ (x - h)^2 + (y - k)^2 = r^2 \] Substitute \( h = 2 \), \( k = -3 \), and \( r = 5 \): \[ (x - 2)^2 + (y + 3)^2 = 25 \] This helps students connect geometric definitions with algebraic expressions.
