"a" is always the number before the x(squared) term
"b" is always the number before the x term
"c" is always the number with no x
Factorising
-------------
•Find 2 numbers that add to make the number without x and multiply to make the number with x
•write the number in brackets
•take both brackets and take off the brackets
•make both equations equal to x
complete the square
--------------------
• make sure "a" = 1 (if not then make it 1)
• bring "c" to the right side
• add ( "b" ) (squared)
--------------------
2
• factorise
• square root both sides
• solve for x
