Answer:
C
Step-by-step explanation:
4t² - 9 = 0
Since the given is a difference of two squares then,
4t² = (2t)(2t)
-9 = (3)(-3)
This is by extracting the square roots of 4t² and -9.
The solution of the above equation is
4t² - 9 = 0
4t² - 9
= (2t + 3)(2t - 3)
= 2t + 3 = 0; 2t - 3 = 0
= 2t = -3; 2t = 3
= t = ; t =
