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)

Can you factorise numbers on a scientific calculator?
Up till now you can't but hopefully will be able to do so soon.
How do you find the largest cube factor of a number?
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.

How do you prime factorise 20 and give your answer in subscript form?
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.
What is the highest common factor of 735 and 756?
HCF(735, 756) = 21 It can save you a lot of time if you use the fact that for any integers A and B, HCF(A, B) = HCF(A, B-A) That soon gives you small numbers to factorise.
How does knowing one linear factor of a polynomial help find the other factors?
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.
What does factorise fully mean?
Factorise fully is when brackets are involved in the equation
How do you factorise a²-a?
a²-a = a(a-1)
Maths. what is to factorise?
To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5

How do you factorise a question that already has brackets?
The answer will depend on where the brackets are. In general the solution would be to expand all the brackets, combine like terms and then factorise.

How do you factorise these expressions?
In the same way that you would factorise any other expressions that do not contain an equality sign depending on the expressions of which none have been given.
