Answer:
10x^4-15x^3+17x^2-13x+17
Step-by-step explanation:
P-2Q
Replace P and Q with the given values,
4x^4-3x^3+x^2-5x+11-(2(-3x^4+6x^3-8x^2+4x-3)
4x^4-3x^3+x^2-5x+11-(-6x^4+12x^3-16x^2+8x-6)
4x^4-3x^3+x^2-5x+11+6x^4-12x^3+16x^2-8x+6
10x^4-15x^3+17x^2-13x+17
Let the amount of shells collected by Aaron be

and the amount of shells collected by Maria be

respectively. Then the following system of equations should be solved:

First of all, express

out of first equation:

Then, replace

in second equation with found expression and solve it:



Finally, replace

in first equation with found value and solve it too:


So, Aaron has found
7 shells while Maria has found
21.
