Question 922715
a) {{{4}}}
.
.
.

b) {{{6x-5=0}}}
{{{6x=5}}}
{{{x=5/6}}}
.
.
{{{x+4=0}}}
{{{x=-4}}}
.
.
{{{5x-2=0}}}
{{{5x=2}}}
{{{x=2/5}}}
.
.
{{{x+8=0}}}
{{{x=-8}}}
.
.
.

c) When {{{x=0}}},
{{{P(0)=(-5)(4)(-2)(8)}}}
{{{P(0)=320}}}
(0,320)
.
.
.
d)Same as b).
.
.
.

e){{{6x-5=6(x-5/6)}}}
{{{5x-2=5(x-2/5)}}}
So then,
{{{P(x)=30(x-5/6)(x+4)(x-2/5)(x+8)}}}
