A second-order algebraic equation, also known as a quadratic equation, is an equation of the form:

ax^2 + bx + c = 0

Where ( a ), ( b ), and ( c ) are constants, and ( x ) is the variable. The highest power of( x ) is 2, hence the term "second-order"

.

To solve a quadratic equation, you can use various methods such as factoring, completing the square, or using the quadratic formula:

[ x = {{-b +_ sqrt{{b^2 - 4ac}}}}/{{2a}} ]

Here are a few examples of solving quadratic equations:

1. **Example 1:** Solve ( 2x^2 - 5x + 2 = 0 ). **Solution:** You can either factor the equation or use the quadratic formula to find the values of ( x ).

2. **Example 2:** Solve ( x^2 + 3x - 4 = 0 ). **Solution:** Again, you can factor the equation or use the quadratic formula to find the solutions for ( x ).

3. **Example 3:** Solve ( 4x^2 - 12x + 9 = 0 ). **Solution:** You can apply the quadratic formula directly to find the values of ( x ).
