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.
\[-9\cdot x=-6\cdot x^2+8\]
The centre column shows the steps in words, and the right column shows the equation after the step is applied.
\[-9\cdot x=-6\cdot x^2+8\]
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
- determine solutions
- calculate discriminant
- reduce to #0#
- determine number of solutions
- determine #a#, #b# and #c#
- #a=6#, #b=-9# and #c=-8#
- #6\cdot x^2-9\cdot x-8=0#
- #D=273#
- #D \gt 0#, hence, there are #2# solutions
- #x={{9-\sqrt{3}\cdot \sqrt{7}\cdot \sqrt{13}}\over{12}} \lor x={{\sqrt{3}\cdot \sqrt{7}\cdot \sqrt{13}+9}\over{12}}#
