Question

Given: AP=2x squared+17x-11
PB=3x squared+3x-4
AB=90

Find AP.

Answer 1

We need to know where the points are in relation to one another.

Answer 2

So AP+PB =AB
2x^2+17x-11+3x^2=3x-6=90

Answer 3

5x^2+20x-17=90

Answer 4

5x^2+20x-15=90
5x^2+20x-105=0
x^2+4x-21=0
(x+7)(x-3)=0
x=-7 or x=3
AP=2(3)^2+17(3)-11
AP=18+51-11=58

Answer 5

thanks a lot :)
