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.
\[4\cdot p=-8\cdot p^2+8\]
The centre column shows the steps in words, and the right column shows the equation after the step is applied.
\[4\cdot p=-8\cdot p^2+8\]
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
- determine number of solutions
- determine #a#, #b# and #c#
- reduce to #0#
- #D=272#
- #p={{-\sqrt{17}-1}\over{4}} \lor p={{\sqrt{17}-1}\over{4}}#
- #8\cdot p^2+4\cdot p-8=0#
- #a=8#, #b=4# and #c=-8#
- #D \gt 0#, hence, there are #2# solutions
