The centre column shows the steps in words, and the right column shows the equation after the step is applied.
- step 1
- step 2
- step 3
- step 4
- step 5
- determine number of solutions
- calculate discriminant
- determine solutions
- reduce to #0#
- determine #a#, #b# and #c#
- #D \gt 0#, hence, there are #2# solutions
- #D=97#
- #6\cdot s^2+7\cdot s-2=0#
- #a=6#, #b=7# and #c=-2#
- #s={{-\sqrt{97}-7}\over{12}} \lor s={{\sqrt{97}-7}\over{12}}#
