If the second polynomial is x + 2y -3, we multiply
    (4x - 3y + 5) (x + 2y - 3)

We distribute each term of the first polynomial (4x - 3y + 5) to every term

of the second polynomial (x + 2y - 3):
    (4x - 3y + 5) (x + 2y - 3) = 4x^2 + 8xy - 12x
                   - 3xy      - 6y^2 + 9y
                        + 5x          + 10y - 15

Then combine similar terms:
    (4x - 3y + 5) (x + 2y - 3) = 4x^2 - 6y^2 + 5xy - 7x + 19y - 15

If the second polynomial is x + 2y --3, we multiply
    (4x - 3y + 5) (x + 2y + 3) = 4x^2 + 8xy + 12x
                                                        - 3xy          - 6y^2 - 9y
                          + 5x          + 10y + 15

    (4x - 3y + 5) (x + 2y - 3) = 4x^2 - 6y^2 + 5xy + 17x + y + 15

What are the options

Answer from: Quest

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
