+/- 4 is read as plus or minus 4 | Shorthand for +4 and -4 |
Steps to solving | one: If coefficient of x^2 is 1 then go to step two but if not then divide both sides by coefficent two: Isolate all variable terms on on side 3: add the square of the coefficient of x to both sides 4:factor 5:square root to solve for x |
