Quick math problem, help pl0x!

[ShizKnight]

So, I need a little help.

Find x.

x^2 - 4x + 4 = 9

Could someone help me, shouldnt take more then a few seconds.

(x-2)^2 = 9
x-2=+,-3

5, -1.

omg, i was planning to do that on a problem on my finals this year if my grades were super

apply pemdas, combine like terms....do the simple stuff....and ushould get x=5

[NuclearSilo]

piece of cake!

x² - 4x + 4 = (x - 2)² = 9
<=> x - 2 = 3 or x - 2 = -3
<=> x = 5 or x = -1

its been explained like 10 times, but your was the most complexed written =.=

X^2-4x+4=?
X1^2-4x+4=?
2-4x+4=? 4x2x+4=?
4x+4=?
ans 16

ok let me try it

first put the 9 over the equals sign to make this equation:

x^2 -4x -5

then factorise it it will become this:

(x-5)(x+1) right?

so x=5 or x=-1 correct?
