Question

Need help answering asap

Answer 1

me thank thats spozed tu be

x^2+x-3=0

if so, yu yuze quadratik equashun

get x=1.3027756 & x=-2.3027756

-b/2a=-0.5

b^2 -4ac=13, so get root(13)=3.605551275

root/2a=1.8027756377

Answer 2

????????? maebee that shood be 10x^2 +x -3=0 ????????

then get (x-0.5)*(x-0.6)=0

"diskriminut"=b^2 -4ac=121, root(121)=11, root/2a=0.55
