The **Quadratic Formula** solves for 'x' in any `ax^2+bx+c=0`.
Formula: `x = (-b ± sqrt(b^2 - 4ac)) / 2a`
Pro-Tip: It's your universal tool – always works, even when factoring fails!

Logarithms (log_b(x)=y) are the inverse of exponentiation, asking b to what power gives x? Ex: log_2(8)=3 because 2^3=8. Pro-Tip: Convert to exponential form (b^y=x) to simplify complex problems!
FTC Part 2 connects definite integrals to antiderivatives. Formula: ∫[a,b] f(x)dx = F(b) - F(a) (where F'(x)=f(x)). Pro-Tip: It makes calculating the exact 'area under a curve' super efficient – just find the antiderivative & plug in!
