A friend of mine asked me if I could help her with a few math questions but my brain doesnt seem to be working very well after last night.

Could someone help me with the anwers to the following questions?

Thanks in advance!

Factor:

t^2-2t+(3/4)

Solve for x:

x^4-13x^2+36=0

Solve for x:

x^4-13x^2+36=0

1.

x = 1.5 or 0.5

2.

This is just a straightforward quadratic too!

Imagine x²=y; then solve y²-13y+36=0. It boils down to y=4 and y=9.

So, x=2 or x=3.

Bob, quite obviously you've just found another excuse to prevent yourself from gardening

I know it's only VfB but I like it!

Thanks for the help Bob.

Sorry to pester guys you with one more question:

Solve:

(6/x)+3/(x+2) =2

The one who helps will get a beer the next time he/she comes to vienna.

Thanx

Solve:

(6/x)+3/(x+2) =2

The one who helps will get a beer the next time he/she comes to vienna.

Thanx

(6/x) + 3/(x+2) = 2

6(x+2) +3x=2(x+2)(x)

6x + 12 + 3x = 2x^2 + 4x

0=2x^2 - 5x - 12

x=4

x also has another value but I don't feel like figuring that one out right now.

6(x+2) +3x=2(x+2)(x)

6x + 12 + 3x = 2x^2 + 4x

0=2x^2 - 5x - 12

x=4

So, x=2 or x=3.

If x²=y and y=4 or y=9 than x=2,**x=-2**, x=3 and **x=-3**!!!
