Answer:
( a+b) (a-b)
x^2 - 50
Step-by-step explanation:
The formula for difference of squares is
a^2 - b^2 = ( a+b) (a-b)
121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares
x^2 - 16y^2 = (x)^2 - (4y)^2 so this is the difference of squares
9x^2 -64 = (3x)^2-8^2 so this is the difference of squares
x^2 - 50 = (x)^2 - 2*(5)^2 this is not the difference of squares
Since, the angle between the machine and angle of press is 
as shown in the attached image.
Therefore, the actual weight lifted by the power lifter is given by 
where 'w' stands for the weight being lifted and 
is the angle of press.
Now,
actual weight lifted by the power lifter = 
= 
pounds.
D = {x|x is a whole number}
E = {4}
F = {2, 4, 6, 8}
D ∩ F = {2, 4, 6, 8}
