If you mean: y2+5y+6 then it is (y+2)(y+3) when factored completely
(3z + 5)(z -7)
It is (x+6)(x-4) when factored
It is irreducible, it can't be factored.
xxxii or XXXII in Roman numerals is equivalent to 32 and 32+18 = 50 which is L as a roman numeral
If you mean: y2+5y+6 then it is (y+2)(y+3) when factored completely
This expression can not be factored. It is already in it's simplest state.
(3z + 5)(z -7)
It is (x+6)(x-4) when factored
If you mean 5x^2 -125 then it is 5(x^2 -25) when factored
27-y3 factored completely = 24
If an expression does not have a common factor, then it is called a "prime" expression.
45
It is irreducible, it can't be factored.
a3-4a = a(a2-4) when factored
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
It's the general form of a quadratic expression and it can be factored providing its discriminant is not less than zero.
