Answer:
Step-by-step explanation:
1176=7 weeks
3 weeks=504
Fourth degree polynomial
might be called quartic
we have
One way to use mental math is to add to both and
so
therefore
the answer is
Factor every numerator and denominator.
x^2-7x+6= (x-1)(x-6)
x^2-x-30= (x-6)(x+5)
x^2-25= (x+5)(x-5)
x^2-1= (x+1)(x-1)
Simplify the first term by cancelling out (x-6) in both the numerator and denominator
(x-1)/(x+5)* (x+5)(x-5) / (x+1)(x-1)
Now cross simplify cancelling out (x-1) and (x+5)
1/1* (x-5)/(x+1)
Final answer: R
