The first two problems I need help with
![Name:
Messy Algebra Project
For each problem, show your work on a separate sheet of paper... that is, only one
problem should appear on each sheet of paper.

1. Simplify: 1+

2. Prove the following statement is true! Hint: pick one of two ways... a) reduce the left
side before multiplying out [you will need to look up a factoring formula for 1–- x" ]. b)
Use the fact that 12÷4=3 IF 3-4=12... so, this way is a lot more multiplying.
(1- p')(1- p°)(1– p')
(1-P')(I-p°)(1-p')
+ p2
= 1+p+2p° +3p° +4p* +4p° +5p° + 4p' +4p* +3p +2p° + p"
3. Consider the TWO solutions to ax +bx+c=0_given by the quadratic formula:
a. Find and simplify the sum of the two solutions.
b. Find and simplify the product of the two solutions.
4. Consider P =-}x² + 220x-9500
a. Find its vertex.
b. Find its y-intercept.
c. Approximate its x-intercepts.
d. Accurately graph the function [include the items found in a, b, and c]!
Graph hint: Scale is important. for instance I used x from 0 to 1000.
What to turn in?
