and also another qn which i am not sure it belong to which catagory so i just post it here together with the previous qn.
the cubic polynomial is such that the coefficient of is -2 ans the roots of the eqn f(x)=0 are 0.5,2 and k
Given that f(x) has a remainder -20 when divided by (x+2), find the value of k.
thanks for your help. however i dont understand one thing. the qn mentioned that coefficent is -2 for x^3 but it did not mention for others.what if there are other coeficent for x^2 for something?will it have a differnet ans?
And also kindly help me solve the 1st qn i asked. Thanks
