Both Sides of the Equation

100

rad x+10= 20

x=-4 or x=5

200

Double the points if you get this correct!

(x+9)²=25

x=-4 or x=-14

300

x²+8x+16=8

x=-4+2 rad 2 

or 

x=-4-2 rad 2

400

rad x²+10x+10=10

x=0 or x=-10

500

rad x²-3+6=18

x=rad 15 or x= - rad 15

Quadratic Formula

100

x²+5-0=0

x=0 or x=-5

200

x²+2+4=0

x=-1 rad 12

or 

x=-1+ rad 12

300

rad x+20= x

x=-4

or 

x=5

400

5x²+5x=-5

x= -1 + rad -75 /2

or

x= -1- rad 75 /2

500

rad x-2 - rad 2x -3 <0

x>-5

Factoring

100

(10x)=-60

x=-6

200

4x²+10x=0

x=0 or x= -5/2

300

x²+2x+5=0

x=-2

or

x=1

400

x²+6x=1

-3+ rad 10=x

or

-3- rad 10=x

500

3x²+9-39

x= rad 10 or x= rad -10
