Factorising 15x-27xy gives 3x (5 - 9y).
Factorising is to express a number or expression as a product of factors.
When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)

Up till now you can't but hopefully will be able to do so soon.
The answer depends on how good you are.You can either factorise the number completely and express it in terms of the exponents of its prime factors. Any prime with an exponent of 3 (or a multiple of 3) is a cube factor.A faster, but more demanding way is to see if 8, 27, 64 ... are factors.The answer depends on how good you are.You can either factorise the number completely and express it in terms of the exponents of its prime factors.

Factor out each prime by prime to obtain: 4 x 5 = 2 x 2 x 5 So the answer is 2² x 5 * * * * * and the word is "superscript", not subscript.
If you know one linear factor, then divide the polynomial by that factor. The quotient will then be a polynomial whose order (or degree) is one fewer than that of the one that you stared with. The smaller order may make it easier to factorise.
2a + 4b + 8c = 2(a + 2b + 4c) You could also continue by factoring the inside of the parentheses a bit: 2a + 4b + 8c = 2(a + 2b + 4c) = 2(a + 2[b + 2c])
