-whatever the answer is, but positive
Absolute value brackets in equation - ✔️✔️-take out brackets
-turn into two equations; one positive answer, one negative
-solve for x for both equations
-two answers
Adding fractions - ✔️✔️-find least common denominator
-multiply each numerator by however much it's denominator was multiplied
-add new numerators, keep denominator
-SIMPLIFY
Subtracting fractions - ✔️✔️-find least common denominator
-multiply each numerator by however much it's denominator was multiplied
-subtract new numerators, keep denominator
-SIMPLIFY
Quadratic formula - ✔️✔️x= -b + or - radical (b squared - 4ac) all over 2a
