FactorInteger[457890]and then press enter, on the bottom right of the keyboard where the numbers are AND NOT return. This produces
{{2, 1}, {3, 1}, {5, 1}, {15263, 1}}as output.
Here I typed in
Solve[x^3 + 2x + 1 == 0, x]Note the x after the comma at the end since that is what i want to find. Also have == and not =. This produces the horrible with many square roots. So if I just use NSolve, same as above except add an N. This gives me something like:
{{x -> -0.453398}, {x -> 0.226699 - 1.46771 i}, {x -> 0.226699 + 1.46771 i}}
