plz plz help im not unerstanding this plz take me thru it step by step
-
foil (a+1)(a+1)=a^2+a+a+1=a^2+2a+1
-
It's not an equation, therefore it cannot be solved.
It can be multiplied out to
a² + 2a + 1
It can be multiplied out to
a² + 2a + 1
-
(a+1)^2,
(a+1)(a+1),
a^2+a+a+1,
a^2+2a+1.
Answer: a^2+2a+1.
