Question 38755: solving quadratic functions of the form f(x)=a(x-h)2+k....(that 2 is a squared)
i know how to get the value of a,h,k, but i dont know what they mean when they say choose some values for x. in example 1 they have 7 values for x, but in example 2 they have 5 values for x.... so how do you know how many numbers to chose forthe value of x?

Question 40108: This is actually about "unfoiling". Is there a quick and easy way to figure out the binomials when unfoiling. As an example:
2x^2 - 9x + 4. How do I know how to choose the right numbers to factor this into two binomials? Is there a different rule for positive and/or negative numbers.
Thanks very much.
