Solve by factoring

Quadratic equations represent any equation that can be rearranged in standard form (
a
x
2
+
b
x
+
c
=
0
ax
2
+bx+c=0) where the value of x is unknown, and the values of the coefficients (a, b & c) are known.

Quadratic equations can always be solved using the quadratic formula, but sometimes factoring or isolating the variable is also possible
