Week 5 Day 2: Solving Quadratics

x = -2 or x = -15

x = -3 or x = 5

x = -5 or x = 3

x = -2 or x = 3

x = 2 or x = 8

x = 1 or x = 2

x = -2 or x = 2

x = 2 or x = 4

x= $-\frac{1}{5}$ or x = 2

 $x=5\ \ \ \ or\ \ \ \ x=-2$  

x = -1 or x = 2

x = -5 or x = $\frac{1}{2}$

x =  $\sqrt{8}$  

x = 0

x =  $1\ -\sqrt{8}$    or  x=  $1\ +\sqrt{8}$  

x =  $-1\ -\ 2\sqrt{2}$    or  x=  $-1+2\sqrt{2}$  

x = -1  or  x= 5

x = -3  or  x= 3

x = 5

x = 1

x = -2  or  x= 2

x =  $-\sqrt{2}$    or  x=  $\sqrt{2}$  

x =  $-\sqrt{14}$    or  x=  $\sqrt{14}$  

x = -14  or  x= 14

x = -8 or x= 8

x = $-\sqrt{72}$ or x = $\sqrt{72}$

x = $-6\sqrt{2}$ or x = $6\sqrt{2}$

x = $-\sqrt{68}$ or x = $\sqrt{68}$

x = -2 or x = 2

x = 2

x = $-\sqrt{12}$ or x = $\sqrt{12}$

x = -4 or x = 4

x = -½

x = -2

x = 0

x = ½

 $x=-1$  

 $x=1\ \ \ and\ \ \ x\ =\ i\sqrt{3}$  

 $x\ =\ -1\ -\ i\sqrt{3}$  and  $x\ =\ -1\ +\ i\sqrt{3}$  

 $x\ =\ 1\ -\ i\sqrt{3}$  and  $x\ =\ 1\ +\ i\sqrt{3}$
