Answer 1

(х+1)*(х+5)-(х+2)*(х-а)=5
х2+х+5х+5-(х2+2х-ах-2а)=5
х2+6х+5-5-х2-2х+ах+2а=0
4х+ах+2а=0
ах+2а=-4х
а*(х+2)=-4х
а=-4хх+2

Answer 2

$(x+1)(x+5)-(x+2)(x-a)=5 \ x^{2} +6x+5-( x^{2} -2 x- alpha x-2 alpha )=5 \ x^{2} +6x+5- x^{2} +2 x+ alpha x+2 alpha =5 \ 4 x+ alpha x+2 alpha =0 \ alpha (x+2)+4 x=0 \ a(x+2)=-4x \ a=- frac{4x}{x+2}$
