Answer:
Step-by-step explanation:
hello :
(x + 2)2 – 2(x + 2) – 15 = 0
let : t= x+2
t²-2t-15 =0
(t-5)(t+3)=0
t-5=0 or t+3=0
t=5 or t=-3
but : t =x+2
if : t=5 x+2 =5 so : x=3
if : t= -3 x+2 = -3 so : x= -5
conclusion two solutions : 3 , -5
Answer:
If this is what your looking for, the answer may be:
