Personal notes

Common algebric identities:

This sentence uses $` and `$ delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$

  • $(a+b)^2 = a^2 + 2ab + b^2$
  • $(a-b)^2 = a^2 - 2ab + b^2$
  • $a^2+b^2 = (a+b)^2 - 2ab$
  • $a^2-b^2 = (a+b) - (a-b)$
  • $(a+b+c)^2 = (a^2 + b^2 + c^2) + 2(ab + ac + bc)$
  • $(a^2 + b^2 + c^2) = (a+b+c) - 2(ab + ac + bc)$
