Answer:
4
Step-by-step explanation:
I would say its the second one.
the student shouldve distributed the 2^3x+3 into 2^3x+9
1.25 - 0.5 = 0.75
1.25 hours = 1 hour 15 minutes
0.5 hours = 30 minutes
1 hour 15 minutes - 30 minutes = 45 minutes
Answer: the fourth option (5p - 2)(5p + 2) (5p - 2i) (5p + 2i)
Explanation:
1) Express the given expression as the difference of two squares:
625p⁴ - 16 = (25p²)² - 4²
2) Factor as the product of a sum times its difference:
(25p²)² - 4² = (25p² - 4) (25p² + 4)
3) Factor each binomial (again square of a difference and sum times its difference):
25p² - 4 = (5p)² - 2² = (5p - 2)(5p + 2)
25p² + 4 = (5p)² - (2i)² = (5p - 2i)(5p + 2i)
4) Therefore, the 4 factors are:
(5p - 2)(5p + 2) (5p - 2i) (5p + 2i)
