+8262 What is ±? What does it mean? Can somebody explain it to me please? Thanks.
+4473 ± means you apply both addition and subtraction.
Near the end of the quadratic formula, you will end up with a general solution such as: (# ± #) / #.
This means you have to apply both the + and the -, which gives you two answers rather than just 1.
Example: 5 ± 3 = both 8 and 2.
