Solve the following questions involving fundamental operations on polynomials

a. Find p(x) + 4q(x)

p(x)=4x^4 + 55x^3 - 23x^2 + 13

q(x)=43x^4+ 14x^2 -12

b. Find P(-1/2) if

P(x) = 2x^4 + x^3 + 12

c. Simplify: (-4 + x^2 + 2x^3) - (-6 - x + 3x^3) - (-6y^3 + y^2)

d. Add: (2x^2 + 6y^2 + 4z^2 + 3xy + yz + zx) + (4x^2 + 3y^2 + z^2 - 3xy - 9yz + 5zx)

e. Multiply: (3x + 3y)^2

f. Multiply: (3x + 4) (3x - 4)

g. Divide: (2x^3 - x^2 + 3x -1) ÷ (x + 2)

B. Factor completely:

a. x^2 - 7x - 9x + 63

b. 4x^2 + 34x + 42

c. x^8 - 1

C. Solve the following problems involving applications of polynomials.

a. A photo is 3 inches longer that it is wide. A 2-inch border is placed around the photo making the total area of the photo and border 108 square inches. What are the dimensions of the photo?

b. A rectangular parking lot is 100 ft longer than it is wide. Determine the dimensions of the parking lot if it measures 500 ft diagonally.
