Answer:
25x² + 144 = (5x + 12i) (5x - 12i).
Step-by-step explanation:
We have to factorize the expression 25x² + 144, using the complex number.
Now,
can be treated as the complex number as there is negative value with in square root.
So,
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)
Answer:
66 degrees
Step-by-step explanation:
assuming that the line RN crosses line QO in the mid point, and that from that point to R, and to N, are the same length, then the angles R and N should be the same making angle O the complimentary angle, that would be 66 degrees
