to put into brackets
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)
For each of a list of algebraic expressions, find one or more common factors and factorise the expression.
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.
