Quadratic Equations Quiz
Quadratic equations are termed as those equations where the highest power or degree of the equation is \(2\). The standard form for a quadratic equation is \(ax^2 + bx + c = 0\), where \(a ≠ 0\). Now, let’s learn to solve quadratic equations by taking the example of equation \((x – 5)(x + 3)\).
- First, let’s apply the distributive law to simplify the equations as \((x – 5)(x) + (x – 5)(3)\)
- By further simplification and application of distributive law we get: \(x^2 - 5x + 3x – 15\)
- Now, let’s combine like terms to get: \(x^2 - 2x – 15\).
