to put into brackets
Factorise fully is when brackets are involved in the equation
If you mean: 2x+10 then it is 2(x+5)
I assume you mean...., 8X + 16 8(X + 2) ======
If you mean: 3x+12 then it is 3(x+4) when factorized
a²-a = a(a-1)
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
If you mean: xsquared+8x-48 then it factors to (x-4)(x+12)
Do you mean: factorise: 27x2-18x-18 best I can get is: 9((3x-2)-2)
The question is not phrased clearly enough to answer exactly; what does "starts with a number" mean?If you mean not starting with a constant number at the beginning, this is common, as most functions are written in order of the highest power of the variable first; you will first need to rearrange the expression to a suitable order.If you mean that the x2 or x terms do not have coefficients (numbers written next to them as ab, meaning "a multiplied by b") then these are easier to factorise; a lack of coefficient simply means "multiplied by one". Further questions can explain how to factorise further.
Do you mean: 3x2-17x+10? If so then it is: (3x-2)(x-5)
you do (245x)
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.
