Answer:px=7x3−2x2+20x−55p(−2)

Step 1: Add -110p to both sides.

px+−110p=7x3−2x2+110p+20x+−110p

px−110p=7x3−2x2+20x

Step 2: Factor out variable p.

p(x−110)=7x3−2x2+20x

Step 3: Divide both sides by x-110.

p(x−110)

x−110

=

7x3−2x2+20x

x−110

p=

7x3−2x2+20x

x−110

Answer:

p= 7x3−2x2+20x /x−110

Step-by-step explanation:

You are substituting the -2 for any x that isn’t multiplication. In this case just the 20x.

P(-2)=7*3-2*2+20* (-2)-55
=21-4+(-40)-55
=17-95
The answer is -78
