or, put simply: ___________________________________ " x² − bx <span>− c = 0 ;
in which: b = - (insert number); and "c" = - (insert number); ___________________________________ Then, the expression on the "left-hand side" of the equation is "factored"; and set equal to "0" . ___________________________________ Note of interest: This is done even if "factoring" cannot be done; and/or if one wishes to proceed using the "quadratic equation formula" to solve for "x". ___________________________________ Hope this helps!</span>
