Study Notes
Quadratic Equations
- Definition: A polynomial equation of degree two.
- Standard form: ( ax^2 + bx + c ), where ( a \neq 0 ).
Perfect Square Trinomial
- A perfect square trinomial can be expressed as ( (x + p)^2 = x^2 + 2px + p^2 ).
- To determine the constant term required for a trinomial to become a perfect square, take half of the coefficient of the linear term, square it, and add it.
Solving Quadratic Equations
- The universal method for solving quadratic equations applicable to all types is the Quadratic Formula: [ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ]
- One alternative method includes Extracting Square Roots.
Factors and Roots
- A quadratic equation can be factored into the form ( (px + q)(rx + s) ).
- The roots (solutions) of the equation can be determined by setting the factored equation to zero.
Coefficients
- In the quadratic equation ( 6x^2 + 7x - 3 ), the coefficients are:
- ( a = 6 ) (quadratic term)
- ( b = 7 ) (linear term)
- ( c = -3 ) (constant term)
General Questions
- Any equation of the form ( ax^2 + bx + c ) where ( a \neq 0 ) is classified as a Quadratic Equation.
- Finding the specific constant term to create a perfect square involves mathematical manipulation of coefficients.
Good Luck!
- Prepare to apply these formulas and concepts when solving quadratic equations.
