According to the Rational Root Theorem, which could be a factor of the polynomial f(x) = 60x^4 + 86x^3 – 46x^2 – 43x + 8? x – 6 5x – 8 6x – 1 8x + 5

OpenStudy (welshfella):

60 * 8 = 480 so we look for factors of 480

d?

OpenStudy (welshfella):

theres one more obvious than that

OpenStudy (anonymous):

hm...b?

OpenStudy (welshfella):

x - 6 is a possible root - not saying that it is but its first one you should try out

OpenStudy (welshfella):

6x - 1 is also a possible factor

OpenStudy (anonymous):

i got C?

OpenStudy (welshfella):

yes C 6x - 1 is a possible factor
