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.
\[-5\cdot p=-6\cdot p^2+7\]
The centre column shows the steps in words, and the right column shows the equation after the step is applied.
\[-5\cdot p=-6\cdot p^2+7\]
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
- reduce to #0#
- determine solutions
- calculate discriminant
- determine #a#, #b# and #c#
- #6\cdot p^2-5\cdot p-7=0#
- #D=193#
- #D \gt 0#, hence, there are #2# solutions
- #p={{5-\sqrt{193}}\over{12}} \lor p={{\sqrt{193}+5}\over{12}}#
- #a=6#, #b=-5# and #c=-7#
