\[\frac{ -b \pm \sqrt{b^2-4ac}}{ 2a } \]
calculusxy
  • calculusxy
\[\frac{ -0 \pm \sqrt{0 - 4(-20)} }{ 2 }\]
anonymous
  • anonymous
yes

i thought the new equation would be like: \[v^2 + 0a - 20 = 0\]
calculusxy
  • calculusxy
\[\frac{ -0 \pm 8.9 }{ 2 }\]

0v would be better, but yes. v^2 +0v -20 = 0
Nnesha
  • Nnesha
v^2 -20 is same as `v^2 -0v -20`
Nnesha
  • Nnesha
well would be great if get the final answer in radical
Nnesha
  • Nnesha
don't take square of 20 factor it out
Nnesha
  • Nnesha
square root*
calculusxy
  • calculusxy
the answer key for this in decimal form...
Nnesha
  • Nnesha
oh okay then.
calculusxy
  • calculusxy
\[\frac{ -0 \pm 8.9 }{ 2 } = 4.45 \]
anonymous
  • anonymous
remember it's \[\pm \]
calculusxy
  • calculusxy
okay so -4.45 or 4.45
anonymous
  • anonymous
yes
Nnesha
  • Nnesha
^ye right it's \[\rm a \pm b ~= a-b ~~ and ~a+b\]
calculusxy
  • calculusxy
is my answer correct?
anonymous
  • anonymous
yes it is. if your key says 4.4721... it's only because you cut off some decimals from 8.9
Nnesha
  • Nnesha
i didn't get 4.4 `5`
anonymous
  • anonymous
but you did solve it correctly.
