I say yes! Embryonic cells should be used TOTALLY to human research!!!! Embryos are not humans. Kill them if needed to save REAL living humans! We should not create them for just that, but once they are to discarded, then use them for science

In terms of believing that there are other life forms out there... and earth is just considered a "grain of sand" in the universe. What if there are other supreme beings out there who actually study us or observe us? I know its crazy, but I got to thinking about it last night and the universe is endless! Think about it!

The following equation is the expression of the left hand side as a sum of partial fractions with rational numbers as coefficients. On the right hand side, A and B are constants and the numerator of the third term is missing

x^3−14x^2+26x−11/ = A/ . . . +B/ . . . . . . C/
. . (x−2)^2(x^2+3). . . .(x−2) . (x−2)^2 . (x^2)+3.

1.Supply the numerator of the last term giving appropriate names to the coefficients.
2.Determine the coefficient B.
3.Determine the remaining coefficients, including those in the missing numerator.
