x + 12x + 20 = (x + 10)(x + 2)
It can not be factored because its discriminant is less than zero
== == y = -x + 5
If you mean: x2-25x+100 then it is (x-5)(x-20) when factored
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
20
4(2b+5)
a2+9a+20 = (a+4)(a+5) when factored
x + 12x + 20 = (x + 10)(x + 2)
If you mean: x^2 +12x +20 then it is (x+2)(x+10) when factored
3x2-7x-20 = (3x+5)(x-4) when factored
6x2+23x+20=0x= .7275 and -4.5634Improved Answer:-6x2+23x+20 = (3x+4)(2x+5) when factored
It can not be factored because its discriminant is less than zero
(x + 5) (x - 4)
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
It is (2x-5)(x-4) when factored
30x2+25x-24x-20 = 30x2+x-20 = (6x+5)(5x-4) when factored
