Hello,
A. Replace 2 with t. I'm assuming the t2 is t to the second power.
4 - 4 = 0
B. 1 - 2(-1) turns out to be 3 as the answer
C. (x + 2)(x + 2) - 2(x + 2) =
X^2 + 4x + 4 - 2x - 4 combine like terms
x^2 + 2x
D. (1.5)(1.5) - 2(1.5)
2.25 - 3
-.75
If t2 is simply (t times 2) then the answers will be as follows:
A. 4 - 4 = 0
B. -2 + 2 = 0
C. (x + 2)2 - 2(x + 2) Distribute
2x + 4 -2x -4 Combine like terms
they cancel out answer is 0
D. (1.5)2 - 2(1.5)
3 - 3 = 0
