 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

 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.

 (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.[Edited 2003-10-01 15:28:13]

 Solved by Bobrayner: 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. If x²=y and y=4 or y=9 than x=2, x=-2, x=3 and x=-3!!!
