I've just seen the following question on a past paper:
"Explain why 5x3 + 2x2 + x = 20 has a solution between x = 1.4 and x = 1.5. Show all your calculations."
In order to answer this question, is it sufficient to simply work out the equation twice gving x the 2 values stated in the question?
I have done that and the 2 solution are:
19.04 (if x = 1.4)
22.875 (if x = 1.5)
