Given polynomials:
21x³ and 28x^5
Factorise each term:
21x³ = 3 x 7 x x³
28x^5= 4 x 7 x x² x x³
So, greatest common factor = 7 x x³ =7x³
Answer: 7x³
Answer:C = 2 π r
r = C / 2 π
r = 907.46 / 2 π
r= 144.42
Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units
Step-by-step explanation:
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)
