four methods of solving a quadratic function

factoring,

completing the square,

quadratic formula,

taking square roots

five methods of factoring learned to date

GCF, g easy, g hard, diff 2 perf squares, pst

4 steps of solving a quadratic function by factoring

- set equation=0
- factor completely (gcf)
- set all =0
- solve for variables

when to solve by taking square roots

b=0

solve by completing the square When

a=1; *b is even

3 forms of a quadratic function

standard vertex intercept

how to complete the square

set=0, factor/banish c value, use appropriate c value on both sides (b/2)^2, factor, sq root, isolate

what is quad formula

x= (-b +- /— b^2-4ac)/2a

what is the discriminant

b^2-4ac

what to use discriminant for

of solutions

3 possible outcomes when solving a quadratic function

D=0: 1 ratl,

D>0 2 real, D
