1
Look at the following equation:
Sometimes there has to be more moved in order to isolate the x2 value.
2
(ax+c)2=0
Missing "b" or "x" term
Doesn't have to =0
Get x2 or the binomial squares by itself before taking the square root.
Don't forget the +/-
3
Multiple Choice
-32 or 32
No Solution
-8 or 8
-64 or 64
4
ax2+bx+c=0
Must be in standard form and =0
If missing "c" term the use GCF Factor (Pull out the biggest number the terms share)
After factoring, Set both factors =0 and Solve for x.
5
Multiple Choice
x= 0 and x= -4
x= 0 and x= 4
y= 0
x= 2
6
Multiple Choice
a2 + 2a - 24 = 0
a = -6, 4
a = 6, -4
a = 12, -2
a = 8, -3
7
Multiple Choice
2x2 + 17x + 21 = 0
x= -21/2, -17
x= 2/3, 16
x=-7, -3/2
x=15, -3/7
8
Must be in standard form and =0
Use when equation is not factorable
ALL QUADRATICS CAN BE SOLVED WITH THE QUADRATIC FORMULA!
9
Multiple Choice
Solve the equation using the quadratic formula.
−10k2−6k+6=0
x=10−3±69
x=−206±269
x=10−3±51
x=−206±251
