OpenStudy (rcp031):

Welcome to OS!

OpenStudy (danieldjpon3):

First solve for x

OpenStudy (danieldjpon3):

But u can't do it yet right?

OpenStudy (danieldjpon3):

x2 - 6x isn't it the same as 2x - 6x?

OpenStudy (danieldjpon3):

So 2x - 6x = -4x am I right?

OpenStudy (rcp031):

x2 - 6x + 9 Splitmiddle term into -3x-3x x^2-3x-3x+9 Grouping:GCF on left is x, on right is−3 x(x-3)-3(x-3) (x+6) is the same, factor out this GCF (x-3)(x-3) Our Solution

OpenStudy (danieldjpon3):

uhh

OpenStudy (danieldjpon3):

Where was I?

OpenStudy (danieldjpon3):

-4 + 9 = 5

OpenStudy (danieldjpon3):

No wait u wil have -4x + 9

OpenStudy (danieldjpon3):

Then u just need to find x

OpenStudy (danieldjpon3):

for example 2 = x

OpenStudy (essence091200):

Im not sure this is my first time actually studying this

OpenStudy (danieldjpon3):

-4 times 2 = -8 then plus 9 = 1
