why are there two of the same problem?

Answer 2

4(t+2)(t-2)

Answer 3

see, the 16 will go other side for simplifying
then it equals 4t^2=16
we divide both sides by 4 to get x^2=4
hence as u can see two values of x will satisfy this equation
that r +2,-2, hence x=+2, x=-2

Answer 4

4t2 − 16=4(t2-4)=4(t+2)(t-2)
