-5 Is Not A Valid Number.
If you mean: 2x2-11x+5 then it is (2x-1)(x-5) when factored
If you mean: 5x+35 then when factored it is 5(x+7)
-5
If you mean 4y+10 then it is 2(2y+5) when factored
45 factored into prime numbers is: 5 x 9 5 x 3 x 3
5(u-5)
-5
It is (x+4)(x+5) when factored
3a - 5 cannot be factored further.
x2 + 6x - 5 is a quadratic expression that can not be factored.
It is: (6y+1)(y-5) when factored
It is: (x-5)(x+1) when factored
