Ocr Core 1 Maths Help!!!!
Can you help me answer this question.
Show that K satisfies
K^2 + 2K - 27 (3 marks)
Hence find the set of possible values of K. (4 marks)
Please don't answer it!!! I just want to know how to answer it.

What you've written doesn't make sense as it stands!
A variable satisfies an equation, not an expression!!!
Can you upload a screenshot of the question?

So for the first part do I just move the 3 over to the other side square root of then divide by 3. Or should I just factorise the equation?
Calculate the discriminant and see what happens

You don't need to move anything anywhere!
Can you answer the question I asked in my previous post regarding a general quadratic equation?
