Understanding Key Formulas and Theorems
Familiarize yourself with the following fundamental formulas and theorems, as they are frequently used to solve problems in this subject:
- Quadratic Formula: For solving quadratic equations, use the formula:
x = (-b ± √(b² – 4ac)) / 2a
This helps to find the values of x when the equation is in the form ax² + bx + c = 0.
- Slope Formula: To calculate the slope between two points (x₁, y₁) and (x₂, y₂) on a graph, use:
m = (y₂ – y₁) / (x₂ – x₁)
This formula helps determine the rate of change or steepness of a line.
- Point-Slope Form: The equation of a line can be written as:
y – y₁ = m(x – x₁)
This form is useful when you know the slope and a point on the line.
- Factoring Quadratics: When solving quadratic equations by factoring, look for common factors or use methods like difference of squares:
ax² + bx + c = (px + q)(rx + s)
Set each factor equal to zero to find the roots of the equation.
- Pythagorean Theorem: In right triangles, the relationship between the sides is given by:
a² + b² = c²
Where c is the hypotenuse, and a and b are the legs of the triangle.
Mastering these key formulas will enable you to solve a variety of problems with greater accuracy and speed.
