# What is the solution set of 2x to the 2nd power -x-15 equals 0?

2x2 - x - 15 = 0 (2x + 5) (x - 3) = 0 [2x + 5 = 0] and [x - 3 = 0] x = -5/2 and x = 3 {-2.5, 3}

# What is integration of x to the power x with respect to x?

Apparently that can't be solved with a finite number of so-called "elementary functions". You can get the beginning of the series expansion here:http://www.wolframalpha.com/in… Continue reading

# What is x to the 3rd power minus 3x to the 2nd power minus 28x?

x3 - 3x2 - 28x = x (x2 - 3x - 28) = x (x - 7) (x + 4) The numerical value of all this, of course, depends on the value of 'x', and it can change in a flash whenever the value… Continue reading

# What is the mass in grams of 5.00 x 10 to the 2nd power water molecules?

The molar mass of H2O = (2 atoms H x 1.00794g/mol H) + (1 atom O x 15.9994g/mol O) = 18.0152g/mol H2O 1 mole of H2O = 18.0152g H2O 1 mole of H2O molecules = 6.022 x 1023 mo… Continue reading

# How do you factor x to the 2nd power minus 16 plus 64?

x2 - 16 + 64 = x2 + 48, which does not have real factors.
