Best ResponseYou've already chosen the best response.0f(x) factorises to (x+1)(x+3)(x2), can you solve the equation now?

Best ResponseYou've already chosen the best response.0i think so. you set each set of parenthesis equal to zero adn solve right?

Best ResponseYou've already chosen the best response.0I don't like these kind of questions because it doesn't necessarily say that f(x) = 0. In my opinion, it should be interpreted as: input a value for f(x) such as x =0,1,2 and simplify the right side: f(0) = (0)^3 + 2(0)^2 + 5(0)  6 f(1) = (1)^3 + 2(1)^2 + 5(1)  6 f(2) = (2)^3 +2*(2)^25(2)  6

Best ResponseYou've already chosen the best response.0No. Hero is wrong. to find out solution we have to set the function equal to zero and solve for x, then we could find three answers of x. Regards, Electronics engineer.

Best ResponseYou've already chosen the best response.0Shayaan, it doesn't matter whether I'm right or wrong. I'm expressing the fact that the question never suggests to set f(x) = 0. It says to find the solutions to f(x) = x3 + 2x2 – 5x – 6 You cannot legitimately argue against what I have posted as a solution to f(x) = x3 + 2x2 – 5x – 6 because by definition, a solution to an equality involving a variable is the variable that makes both sides of the equation equal. With that being the case, I can justify that f(0) = (0)^3 + 2(0)^2 + 5(0)  6 f(1) = (1)^3 + 2(1)^2 + 5(1)  6 f(2) = (2)^3 +2*(2)^25(2)  6 f(n) = (n)^3  2(n)^2  5(n)  6 and really, you can't make a legitimate argument against it whether you're an electronics engineer, a teacher, math professor, or a farmer. The solution I have written by the properties of equality and definition of a function suggest that my solution is also correct.

Best ResponseYou've already chosen the best response.0honestly i wouldnt know if you are right or wrong but when my assignment gets graded. ill let you know. i can always talk to my teacher abotu this but shes not online. ill try to get back to you.

Best ResponseYou've already chosen the best response.0I believe it's pretty immature for anyone to outright suggest that my solution is wrong without justification.

Best ResponseYou've already chosen the best response.0That also includes your teacher shayna. :) If she says it is wrong, she also has to justify why.

Best ResponseYou've already chosen the best response.0oh i know. i just havent spoken to her about it yet. she usually tels me how to solve the problem and i would have told you what she said. im pretty sure you were right though.

Best ResponseYou've already chosen the best response.0Well, I wouldn't say that I'm 100% right, however, I'm definitely not wrong.

Best ResponseYou've already chosen the best response.0Here I want to say some thing. Hero is still wrong. As Hero said,"Shayaan, it doesn't matter whether I'm right or wrong. I'm expressing the fact that the question never suggests to set f(x) = 0. It says to find the solutions to f(x) = x3 + 2x2 – 5x – 6." Now it is a matter that you are doing wrong or right and also this question suggest whether to keep f(x)=0 or not. Don't you know how? Regards, Electronics Engineer.
