Question

x minus 5 a factor of x cube minus 3 X square + 8 x minus 10

Answer 1

The + key means plus, and - key means minus. * ([Shift]-[8]) means times and / means divide. 2+2/3*8 is "two plus two divided by 3 times 8."Webmath always follows the correct "order of operations" on everything you type.Webmath knows when to multiply. So if you have 2(x+1), you don't need to type it at 2*(x+1); type it like 2(x+1).Fractions are typed using the slash, or / key as the fraction bar. So, "two-thirds" would be typed as 2/3. "One-half" would be types as 1/2.Exponents are typed using the caret, or ^ key ([Shift]-[6] on your keyboard). So, 22 would be typed 2^2. x2 would be typed x^2. (x+5)2 would be typed (x+5)^2.You can put a fraction in an exponent. x2/3 should be typed like x^(2/3).With more complicated fractions you have to use parenthesis. For example if you typed x^2+1/x-5, you might think this means "the quantity 'x-squared plus 1' over the quantity 'x minus 5'." Actually, this site would correctly put 1/x as the only fraction. Instead, you should type it like this: (x^2+1)/(x-5).Webmath DOES NOT know about constant like Pi (=3.1415...), and e (=2.718..). If you need these, you can just put them in directly as numbers. Or, you can put P in for Pi and E in for e. Webmath will carry these through in a problem, and you can see what happened at the very end.
