Write as a product:
p^2–(2p+1)^2

Step-by-step explanation:

a² - b² = (a + b)(a - b)

a= p ;    b = 2p + 1

p² - (2p + 1)² = (p + 2p +1) (p - [2p+1] )

                     = (3p + 1) (p - 2p -1)

                     = (3p + 1)(-p - 1)

-(p + 1)(3p + 1)

Step-by-step explanation:

p² – (2p+1)²

(p - 2p - 1)(p + 2p + 1)

(-p - 1)(3p + 1)

-(p + 1)(3p + 1)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
