Quadratic equations: Solving quadratic equations
The quadratic formula 1
Drag the steps to solve the equation below by means of the quadratic formula in the correct order.
\[-8\cdot s=-6\cdot s^2+8\]
The centre column shows the steps in words, and the right column shows the equation after the step is applied.
\[-8\cdot s=-6\cdot s^2+8\]
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
- reduce to #0#
- determine solutions
- calculate discriminant
- determine number of solutions
- determine #a#, #b# and #c#
- #s=-{{2}\over{3}} \lor s=2#
- #a=6#, #b=-8# and #c=-8#
- #6\cdot s^2-8\cdot s-8=0#
- #D=256#
- #D \gt 0#, hence, there are #2# solutions
