Vwhich is a factor of the polynomial f(x) = 6x4 – 21x3 – 4x2 + 24x – 35?

2x-7 is a factor

Step-by-step explanation:

Given is a polynomial

By rational roots theorem the factors can be 7/2 or -7/2

Use remainder theorem

f(7/2) =0

Hence 2x-7 is a factor

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
