Best ResponseYou've already chosen the best response.1My answer for no. 1 is \[3x^3 ( 3x^2/2)  3x + (3/2)\] but my teacher said there should be no fractions

Best ResponseYou've already chosen the best response.0then multiply all the terms by 2(the denominator) to get rid of the fraction

Best ResponseYou've already chosen the best response.1isn't that your answer does not have a leading coefficient of 3 ?

Best ResponseYou've already chosen the best response.1(x1)(x+1)(x1/2) = 0 try again.

Best ResponseYou've already chosen the best response.1I did (x1)(x+1)(2x1) = 0 is it the same as (x1)(x+1)(x1/2) = 0 ??

Best ResponseYou've already chosen the best response.1I got\[x^3+( x^2/2) (x/2)+(1/2)\] I checked it twice :)

Best ResponseYou've already chosen the best response.1We can multiply the equation by 1.5 to make the leading coef as 3. :D

Best ResponseYou've already chosen the best response.12x1 and x1/2 is same.

Best ResponseYou've already chosen the best response.1so my answer I think is \[3x^3 + (3x^2/2)  (3x/2) + (3/2)\] that's the only expression I can have to make the leading coefficient equal to 3

Best ResponseYou've already chosen the best response.13x^3 + 1.5x^2  1.5x + 1.5 NO FRACTIONS!!! :D

Best ResponseYou've already chosen the best response.1it should be P(x) = x^2  10kx + 6

Best ResponseYou've already chosen the best response.1Find the value of k such that x+3 is a product of P(x) = x^2  10kx + 6 (3)^2  10k(3) + 6 = 0 9 + 30 k + 6 = 0

Best ResponseYou've already chosen the best response.1I got k = 1/2 but why did you made x into 3?

Best ResponseYou've already chosen the best response.1Because since it's a product of it, the remainder is 0.

Best ResponseYou've already chosen the best response.1So we insert the factor and set the equation = 0.
