Imaginary Numbers Review Imaginary Numbers Quadratic Forms Converting Standard Form
Imaginary Numbers Remember, when we take the square root of a negative number, we need to use i. The pattern for powers of i looks like this:
Complex Numbers Standard form: Algebraically, we can treat i just like a variable (we can add, subtract, multiply and divide it) To add or subtract, just combine your like terms To multiply, use the distributive property and remember that i^2 = -1! To divide, we can’t have an imaginary number in the denominator, so we must use the complex conjugate.
Quadratics Standard form: Vertex form: Intercept Form: Quadratic Formula: Axis of Symmetry:
Converting to Vertex Form • Use ‘completing the square’ method. Divide ‘b’ by 2 and square to find the ‘new c’
