Answer:
(t^2 -4) (t^2 +4)
(t-2)(t+2)(t^2+4)
Step-by-step explanation:
t^4 - 16
We can write this as the difference of squares
We know the dfference of squares is
(a^2 - b^2) = (a-b) (a+b)
( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4)
We can write t^2 -4 as the difference of squares
t^2 -4 = t^2 -2^2 = (t-2)(t+2)
Replacing this in
( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4) = (t-2)(t+2)(t^2+4)

Step-by-step explanation:
Answer:
1. The equation is given as
324 = 220 +135 + C
2. We have 166 As the correct answer but is not in the option
Step-by-step explanation:
We are been given the following values
No. of trophies = 3
Total Legos required for all trophies = 324
No. of Legos for largest trophy(A) = 220
No. of Legos for smallest trophy(B) = 135
No. of Legos required for final trophy(C) which is unknown
Total legos will addition of everything
Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)]
Substituting the values
324 = 220 +135 + C
Making C subject of formula
324 = 355 + C
324 - 355 = C
-31 = C
135 + 31 = 166
We have 166 As the answer
