Answer:
A) 2
Step-by-step explanation:
4x² - 9 = (px + t)(px - t)
Using formula a² - b² = (a-b)(a+b)
4x² - 9 = (2x)² - 3² = (2x - 3)(2x+3),
so
(px + t)(px - t) = (2x - 3)(2x + 3).
We can see that p = 2, and t = 3.
The value of p should be 2.
Given that,
And,
Now we use the following formula to determine the value of p
We know that
[tex]a^2 - b^2 = (a - b) (a + b)\\\\4x^2 - 9 = (2x)^2 - 3^2 = (2x -3) (2x + 3)[/tex]
Thus,
(px + t ) (px - t) = (2x - 3) (2x + 3)
So, here p = 2, and t = 3
Therefore we can conclude that the value of p is 2
