Question 1018017: I NEED THE ANSWERS ASAP PLEASE
1. Expand and simplify, if possible.
a. (x + 1)(x + 2)

b. (x – 2y)(y – 3x)
c. (2p + 3)(p2 – 4p – 7)
2. Choose values for a and b and use them to verify the product shown.(5a + b)(a – 6b) = 5a2 – 29ab – 6b2
3. Denise has multiplied (2r – 3)(2r + 3) to get 4r2 – 9. After looking at her work, Hyder says her solution must be incorrect because multiplying two binomials will always produce a trinomial. Which student is correct? Explain the error to the incorrect student.
4. The total area of a picture and its frame can be represented by (l + 2f)(w + 2f), where l and w represent the length and width of the picture, respectively, and f represents the thickness of the frame.
a. Sketch a diagram to represent this scenario.

Too many questions. Basic concepts are needed for all of them.

Number 3:
Learn how Difference of Squares is obtained.
%282r-3%29%282r%2B3%29
If using Distributive Property,
2r%2A2r%2B2r%2A3%2B%282r%29%2A%28-3%29%2B%28-3%29%283%29
4r%5E2%2B6r-6r-9
4r%5E2%2B0-9
4r%5E2-9--------------the linear term was 0, and this needs not to be written because it is the Additive Idcentity.
