anonymous · Answer

factoring

solomonzelman · Answer

What about completing the square, b/c the equation is like designed for that!

solomonzelman · Answer

For factoring, your first step would be, to subtract 25 from both sides.

anonymous · Answer

so im subtracting 25 from 36

solomonzelman · Answer

yes!

solomonzelman · Answer

(and on the right side, 25 from 25)

anonymous · Answer

ok then my problem comes to x^2+12x=11

solomonzelman · Answer

No! it is -11, b/c originally when you subtract you get x^2+12x+11=0.

See?

anonymous · Answer

o ok

solomonzelman · Answer

So your equation is $$x^2+12x+11=0.$$

solomonzelman · Answer

Can you factor that?

solomonzelman · Answer

i can give you couple tips on how to factor this, i am sure it will make it much easier!!

anonymous · Answer

x^+1=0

anonymous · Answer

@whiterabbit541

solomonzelman · Answer

Hold on, that is not right!
You need to factor out  the  $$x^2+12x+11=0$$

anonymous · Answer

Is the answer a

solomonzelman · Answer

I'll give you a couple tips on this....

1) All numbers when it is factored are positive.
2) the constants must be 1 and 11

Still need help o how to factor this?
Don't 11 and 1 add to 12?

anonymous · Answer

yes

solomonzelman · Answer

$$(x+11)(x+1)$$  what about now?

solomonzelman · Answer

$$(x+11)(x+1)=0$$
therefore
$$x+1=0$$    or    $$X+11=0$$

So what is x?
