Do as indicated.

1. Multiply (x - y +z - w)² by applying the formula for the square of a binomial three times.

2. Find a polynomial that represents each measurement. Assume that all variables represent positive numbers.

a. The area of a rectangle whose length is (a + 4) units and width is (2 + 2a + 3a²) units

b. The volume of a cube whose length of each side is (2x + 3y)
units

3. Draw a square with an area of (p + 5)² Label the smaller
regions that comprise the square. Explain how the figure can show (p+5)²≠p²+ 25.

4. The sum of the squares of two whole numbers is 1130, while the square of their sum is 1840. Find the product of the two numbers.​
