Solve x^2-3x+1=0 using completing the square method​

This won't be the easiest way to do this problem but as your teacher requires it I will do it that way. But at the end I will show another way to do it with the quadratic formula.

First complete the square

x^2-3x+1=0

(x^2-3x+9/4)+1=9/4

(x-3/2)^2=9/4-1

(x-3/2)^2=5/4

x-3/2=±

x= 3/2±

Done!

*Now this next way is not the way your teacher wants you to do it but I personally think its easier.

Just use the quadratic formula x=[-b±sqrt(b^2-4ac)]/2

x=[3±sqrt(9-4*1*1)]/2

x=(3±sqrt5)/2

x=3/2±sqrt5/2

We get the same answer but I think this way is easier. Now if your teacher ask for the top way just do the top way don't do the bottom because you will lose points, its just a shorter way to do things. Now I hope this helped and any additional questions about this just ask me in the comments.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
