SETTING THE SCENE
In the previous essay we factorized the expressions
\(x^2+5x+6\)
\(x^2+9x+20\)
\(x^2-8x+12\)
\(x^2-5x+6\)
\(x^2+7x+12\)
\(x^2+2xt-15t^2\)
—and more!—with each expression beginning with \(x^2\). But what if the coefficient out front is not \(1\)? We start this essay with that issue.
