Factor the expression completely over the complex numbers: 25x2 +144
Paha777 [63]

Answer:

25x² + 144 = (5x + 12i) (5x - 12i).

Step-by-step explanation:

We have to factorize the expression 25x² + 144, using the complex number.

Now, i = \sqrt{- 1} can be treated as the complex number as there is negative value with in square root.

So, i^{2} = - 1

Therefore, we can write the original expression as  

25x² + 144

= 25x² - (i²)(144)  

= (5x)² - (12i)²

= (5x + 12i) (5x - 12i)

So, the factorization is 25x² + 144 = (5x + 12i) (5x - 12i). (Answer)

Which of the following illustrates the truth value of the given conditional statement? p: 2 + 2 = 4 q: 7 + 1 = 7 T F → F T T → T
musickatia [10]

Answer:

T F → F is the correct answer.

Step-by-step explanation:

In the given question if p illustrates p: 2 + 2 = 4

which is true so the truth value of this statement p is True.

Now the other statement q illustrates q: 7 + 1 = 7

Which is a false statement so the truth value of this statement is False.

As we know when "p→q ( p implication q), the truth value of implication is False only when truth value of p is True and for statement q the truth value is False."

We can see from the truth table truth value of p→q will be False.

So T F → F
