Study Notes
Linear Equations
- A linear equation is an equation in which the highest power of the variable(s) is 1.
Solving Linear Equations
- To solve the equation 2x + 5 = 13, subtract 5 from both sides, then divide both sides by 2, resulting in x = 4.
Quadratic Equations
- The quadratic equation x^2 - 5x + 6 = 0 can be factored as (x - 2)(x - 3) = 0, yielding roots x = 2 and x = 3.
- The sum of the roots of the quadratic equation x^2 - 5x + 6 = 0 is 2 + 3 = 5.
