Answer:

x²-4x+4 =0

x²-4x-x+4 =0

x(x-4) -1(x-4) =0

(x-1) (x-4) = 0

x = 1,4

_____________________________

 \alpha  =  - 5 \\  \beta  = 4 \\ x =  - 5 \\ x = 4 \\ ( x + 5) = 0 \\ (x - 4) = 0 \\ (x  + 5)(x - 4) = 0 \\  {x ^{2}  - 4x + 5x} - 20 = 0 \\ p(x) =  {x}^{2}  + x - 20 = 0

Step-by-step explanation:

Hope this help you
