Best ResponseYou've already chosen the best response.1I call with F(x) the subsequent function: \[F\left( x \right) = {\left( {x  2} \right)^2}g\left( x \right)\] then, applying the product rule, we can write the first derivative of F(x) as below: \[F'\left( x \right) = 2\left( {x  2} \right)g\left( x \right) + {\left( {x  2} \right)^2}g'\left( x \right)\] now please try to factor out x2, what do you get?

Best ResponseYou've already chosen the best response.1here we can write this: \[{x^5} + a{x^4} + 3{x^3} + b{x^2} + a = P\left( x \right){\left( {x  2} \right)^2}\] according to the hypothesis of your problem

Best ResponseYou've already chosen the best response.1where P(x) is another polynomial. Now if I replace x with 2, I substitute x=2 into that equation, what do you get?

Best ResponseYou've already chosen the best response.1hint: the right side is: \[P\left( 2 \right){\left( {2  2} \right)^2} = 0\]

Best ResponseYou've already chosen the best response.1hint: we have: \[{2^5} + a \times {2^4} + 3 \times {2^3} + b \times {2^2} + a = 0\] please simplify

Best ResponseYou've already chosen the best response.1then you can simplify further: what is 32+24=... what is 16a+a=...

Best ResponseYou've already chosen the best response.1ok! so we got this condition or equation: \[56 + 17a + 4b = 0\]
