Algebra Formulas cheat sheet

8 algebra formulas on one page. Print it or save it as a PDF from the print dialog.

Slope
m=y2−y1x2−x1m = \frac{y_2 - y_1}{x_2 - x_1}
Slope-intercept form
y=mx+by = mx + b
Quadratic formula
x=−b±b2−4ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
Difference of squares
a2−b2=(a−b)(a+b)a^2 - b^2 = (a - b)(a + b)
Exponent product
aman=am+na^m a^n = a^{m + n}
Exponent power
(am)n=amn(a^m)^n = a^{mn}
Log product
log⁡b(xy)=log⁡bx+log⁡by\log_b(xy) = \log_b x + \log_b y
Change of base
log⁡bx=ln⁡xln⁡b\log_b x = \frac{\ln x}{\ln b}
