Here's a taster:

±2 -4 To solve a quadratic equation:
2
Use factorisation
2 + + = 0 2 - 4 = 2
Use completion of square
2 + + = 0 2 - 4 > 0; two roots
Use the quadratic formula
2 + + = 0 2 - 4 = 0; one root
2 + + = 0 2 - 4 < 0; zero roots
( + ); translation by - in -axis To sketch a quadratic function:
() + ; translation by in -axis Find…read more
