Part A: Divide (8x4y3 + 4x3y2  2x2y  12x2y4) by 2x2y. Show your work, and justify each step.
Part B: How would your answer in Part A be affected if the x2 variable in the denominator was just an x?
Part C: What is the degree and classification of the polynomial you got in Part A?

Best ResponseYou've already chosen the best response.0you divide each "term" by the denominator can you do the first term \[ \frac{8x^4y^3 }{2x^2y}\]

Best ResponseYou've already chosen the best response.0first do the numbers 8/(2) then x*x*x*x/x*x then y*y*y/y

Best ResponseYou've already chosen the best response.0Divide (8x4y3 + 4x3y2  2x2y  12x2y4) by 2x2y. that means you divide each term by 2x2y the first term is 8x4y3 divided by 2x2y

Best ResponseYou've already chosen the best response.0as you know, \[ \frac{8x^4y^3 }{2x^2y}= \frac{8}{2} \cdot \frac{x^4}{x^2} \cdot \frac{y^3}{y} \]

Best ResponseYou've already chosen the best response.0or, if we expand the exponents for x \[ \frac{8}{2} \cdot \frac{x^4}{x^2} \cdot \frac{y^3}{y} \\ \frac{8}{2} \cdot \frac{x\cdot x \cdot x \cdot x}{x\cdot x} \cdot \frac{y^3}{y} \]

Best ResponseYou've already chosen the best response.0if you have the "same thing" in the "top" and "bottom" they divide out (give you 1) so every x/x can be cancelled.

Best ResponseYou've already chosen the best response.0I have 10 mins and about 20 secs left can you try and help a little faster sorry for rushing I just don't understand

phi

Best ResponseYou've already chosen the best response.0we use the idea that anything divided by itself is 1 \[ \frac{x \cdot x}{x \cdot x} = 1 \]

phi

Best ResponseYou've already chosen the best response.0so \[ \frac{x^4}{x^2} = \frac{x\cdot x \cdot x\cdot x}{x\cdot x}= x^2 \]

phi

Best ResponseYou've already chosen the best response.0\[ \frac{y \cdot y \cdot y}{y} \] you have one y/y pair that you can cancel

phi

Best ResponseYou've already chosen the best response.0you should get \[ \frac{8}{2} \cdot \frac{x^4}{x^2} \cdot \frac{y^3}{y} \\ 4 x^2y^2\]
