]]>Then do this:

A. Add the polynomials

B. Subtract the polynomials

C. Multiply the polynomials.

D. Evaluate the two polynomials when x = 1/7.

]]>A. x^8 - x^5

B. 4 - 14x^2 - 16x^2

]]>Factor each expression completely.

A. 5(2x + 1)^2 + (5x - 6) • 2(2x + 1) • 2

B. (3x^2)(8x - 3) + 8x^3

]]>What makes the difference between the two equations?

]]>thanks

I can help you in this forum with middle school and high school mathematics, if you are interested.

]]>Prove that the two equations have one solution if the following two conditions are satisfied:

B*D = E*A

and

A*E^2 - D*B^2 = 4*A*D*(F-C)

As you know, this is simply a special case.

Your answer is right always. I mean, your condition is satisfied in this case too.

Hint: First draw a sketch.

2. Find the standard equation of the circle tangent to the y-axis and with center (3, 5).

3. Find the standard equation of the circle passing through the origin and with center (3, 5).

4. The points A( 1, 6) and B(3, 2) are the endpoints of a diameter of a circle, as indicated in the accompanying figure. Find the y-intercepts of the circle.

Hint:Could you do the problem if you had the equation of the circle?

Enjoy!

Hi Bob. I totally get it thanks to your diagram.

]]>2. Do you prefer to memorize the rule for the square of a binomial or to use FOIL to obtain the product? Write a brief reason defending your choice.

]]>2. Explain why the degree of the sum of two polynomials of different degrees equals the larger of their degrees.

3. Give a careful statement about the degree of the sum of two polynomials of the same degree.
