If you can read these formulas, you're in Math 2!


If you're at a Math 2 level, you'll probably be familiar with most or all of these sentences and formulas, or you would be able to understand what they meant on a surface level if you were to look them up.

The [-quadratic_formula] states that the roots of every quadratic expression ax2+bx+c are equal to b±b24ac2a. The expression under the Square root, b24ac, is called the [-discriminant], and determines how many roots there are in the equation.

The imaginary number i is defined as the primary root of the quadratic equation x2+1=0.

To solve the system of linear equations ax+by=cdx+ey=f for x and y, the value of x can be computed as bfcebdae.

The [-power_rule] in calculus states that ddxxn=nxn1.

All the solutions to the equation mn=nm where m<n are of the form m=(1+1x)x and n=(1+1x)x+1, where x is any positive real number.
