1. show all work. Find the difference: (-5x2 + 2x – 5) – (7x2 – 2x– 3)

2. Find the product: -3x(-7x2 – 6x + 1)

3. Add (6.1x2 – 8.3x – 0.2) + (-7.8x2 – 0.8x + 7.3)

1. Consider first a linear equation: 3x – 1 = 5.

a. Use a graphing utility to show y1= 2x – 1 and y2=5 and determine the point of intersection. Make a sketch and label it.

b. How does the graph in part (a) relate to the solution set of the equation 3x – 1 = 5?

c. To solve the equation 3x – 1 =5 algebraically, the first step is to add 1 to both sides of the equation. Use a graphing utility to show y1=3x and y2=6, and determine the point of intersection. Make a sketch and label it. How does this graph relate to the equation 3x=6?

d. The final step to solve the equation is to divide both sides of the equation by 3. Use a graphing utility to show y1=x and y2=2, and determine the point of intersection. Make a sketch and label it. How does this graph relate to the equation x=2?

e. The algebraic steps to solve the equation 3x – 1 = 5 produce two equations: 3x=6 and x=2. How do the graphs you sketched above represent the fact that these equations are equivalent to the original?
