Question

lll

Answer 1

so here is the basics if

(x -2) is a factor x = 2 is a zero

substitute
f(2)=(2)3+7(2)2+14(2)+8


its a positive answer... so not a factor...

try

(x + 2) which means x - 2 is a zero substitute and check

f(−2)=(−2)3+7(−2)2+14(−2)+8


if you evaluate it you'll get f(-2) = 0

so (x + 2) is a binomial factor.

hope this makes sense

Answer 2

6x2 - 7x + 2

Answer 3

sorry, left out the first term

Answer 4
