Thực hiện phép tính: a) ( 3 – xy2 )2 – ( 2 + xy2 )2
b) 9x2 – ( 3x – 4 )2
c) ( a – b2 )( a + b2 )
d) ( a2 + 2a + 3 )( a2 + 2a – 3 )
e) ( x – y + 6 )( x + y – 6 )
f) ( y + 2z – 3 )( y – 2z – 3 )

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

answer: the answer is b. i think hope i got it correct
