Math: Advanced and Geometry
This area covers quadratics, functions, exponents, and geometry topics such as area, perimeter, and circles. Recognizing structure, like factored quadratics, often reveals the answer quickly. Knowing the core geometry formulas is essential since only some are provided.
Functions and Quadratics
Evaluate a function by substituting the input for the variable, being careful with signs when squaring. A factored equation such as (x + 2)(x - 5) = 0 gives its solutions immediately by setting each factor to zero. The sum of the roots can be read straight from the factors.
Essential Geometry Formulas
The area of a square is the side squared, so its side is the square root of the area. A circle's circumference is 2 times pi times the radius, which lets you solve for the radius from the circumference. Keep track of which quantity, radius or diameter, the problem gives you.
