solve for v
\[5v^2+15v=0\]
@jhonyy9
Are you able to like explain this? I have multiple questions just like this
are there any options
what are common factor - what can factorize out from every two terms ?
5
just 5 ? no
5v*
there is again yes exactly - so what will get than you factorize out the 5v ?
5v(v+3)?
yes so 5v(v+3) = 0 solve it for v
It asks if it has multiple answers, use a comma and if there is no answer use "nosolution"... is just one answer?
this expression of 5v(v +3) when will be equal zero ? when one of these terms is equal zero - so take them one by one equal zero and solve it for v .
ok ?
Okay i get you but what do you mean by "take them one by one"....? sorry im slow
there are two terms - so this expression will be equal zero if one term from these two is equal zero so in this case we make first 5v = 0 v = 0 and the second term what will be ?
3?
5v(v +3) = 0
5v = 0 v = 0 the second term is v +3 = 0 v = ?
-3
not 3 yes of cors - 3
v = -3
bc. this is a quadratic equation so has two roots ok ?
Okay okay i see what you mean by terms but to clerify, basically any terms =0 then thats the (multiple) answers? Like i know everything up until the terms but it sounds right in my head now
yes - when there is factorized an equation so you need to take every term equal zero and solve them for this variable
\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 yes - when there is factorized an equation so you need to take every term i mean every factor - equal zero and solve them for this variable \(\color{#0cbb34}{\text{End of Quote}}\)
ok ?
I gotchu! Thank you!!!!!
anytime - i m glad to give help
