Math is pretty cool sometimes

Quadratics

100

x²+8x+16=0 

x = -4

200

x²-256=0

x = -16 and x = 16

300

4x²–19x+12=0 

x = 3/4 and x = 4

400

-5x²-14x+4=0

x = (-7+sqrt(69))/5

 and 

x = (-7-sqrt(69))/5

500

-7x²+8x-23=-2x²-10

x = (4-7i)/5

System of Equations

100

3x+y = -3

x = -y+3

x = -3

y = 6 

200

x = 3y + 2x

2y = 4x + 8

x = -12/7

y = 4/7

300

3x = -9 + 3

7y = 5x + 9

x = -2

y = -1/7
