What numbers less than 20 can be factorised with prime numbers only?
Assuming you mean positive whole numbers, then all numbers greater than 1 can be factorised using prime numbers only. Some of the numbers are prime themselves, eg 2, 3, 5, 7 and so factorise into themselves; others are composite and so factorise into the product of 2 primes, eg 8 = 2 x 2 x 2, 12 = 2 x 2 x 3
How do you factorise a2 plus 16?
a2+16 cannot be factored. There are no two numbers whose product is 16 and whose sum is 0.
How do you factorise a²-a?
a²-a = a(a-1)
10s plus 5t?
Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question. What do you want? To evaluate it (impossible), factorise it, something else?
How do you factorise 10X 5?
you do (245x)
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
Can you factorise numbers on a scientific calculator?
Up till now you can't but hopefully will be able to do so soon.

What does factorise fully mean?
Factorise fully is when brackets are involved in the equation
How do you factorise a2 plus 16?
a2+16 cannot be factored. There are no two numbers whose product is 16 and whose sum is 0.
How do you factorise a²-a?
a²-a = a(a-1)
How do you factorise x2-9x-112?
Two numbers differing by 9 whose product is 112? 7 & 16 (x + 7)(x - 16)
10s plus 5t?

What does it mean to factorise?
to put into brackets
How do you factorise 10X 5?
you do (245x)
How do you factorise x squared -2x plus 3?
x2-2x+3 does not factor over the field of real numbers. Over the complex numbers, it factors as (x - 1 +is)(x -1 -is) where s is the square root of 2.
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.
