Understand it now. Should line 1 be 2n instead of 2n^2?
Yes you are right. I am sorry, that was my mistake. I have corrected it. Please see the same PDF link again where my mistake is now corrected.
For Q1, basically we solve simultaneous equations by using Substitution method. I did not get any surds for my answer, so you might want to check the question again.questionable_i wrote:Can anyone help me with these questions?
1. The straight line 3y=6-2x meets the curve (2x+1)^2+6(y-2)^2-49=0 at the points P and Q. Find the point P and Q and leave your answer in surd form.
2. α and β are roots of the equation x^2+2x=h. The quadratic equation 8x^2-6x+k=0 har roots of (1-α)/α and (1-β)/β. Find the values of h and k.
3.Find the range of values of k for which the expression 2(k-3)x-25-x^2 is always negative for all real values of x.
I need it ASAP.
