Are you required to be sure? You should be learning. You may experience periods of wonder and absence of clarity. Complete the square. Find the zeros. Find the intercepts. Find the axis of symmetry. Identify the curve.Im not sure how to sketch the graph y=9-x^2
It didn't. HTML ignores extra spaces. Learn just a hair of LaTex and you'll be there. Think about the Rational Root Theorem. Try to imagine what it has to do with those irrational roots. If a cubic expression has a factor (3x-2), can you write a general quadratic expression with the information from the other two zeros?Also..i dnt know if this will go right on here..
a=3/2 b=9-17(17 in a sqr root) c=9+17(also in sqr root)
You can't, but you may wish to play with (a+b+c)^2 and see what comes out.How can i shpw that a+b+c =abc do i need to add them all and then multiply them all and it should be the same?
