PLEASE ANSWER!! If you were an Algebra 1 instructor and were creating a test on factoring trinomials of the form ax2 + bx + c, what do you think would be the easiest way to create a trinomial that can be factored? Provide one unique example.

    If you meant equations only dealing with x on the left-hand side, then these are other, simple possibilities: \[(x+1)^2 = x^2 + 2x + 1\] \[(x+1)(x-1) = x^2 -1\] \[(x-1)^2 = x^2 -2x + 1\] He'll likely use one that's of this form, but with additional numbers in front of the first x term, for instance.

    I would choose any equation that looked like it was already factored, and then expand it out. Basically something of them form \[(x+a)(x+b)\]where \(a\) and \(b\) are constant (integers). An example would be to take \(a=-3,\; b=2\). So\[(x-3)(x+2)\]\[x^2-3x+2x-6\]\[x^2-x-6\] So my question would ask to factor \(x^2-x-6\)
