Question

y=-x-2 , y=-2x^2+x-3 solve algebraically please help!!!

Answer 1

solve \[-x-2 =-2x^2+x-3 \]

Answer 2

i got -2x^2+2x-1=0 but i dont know where to from there

Answer 3

write is all on one side of the equal sign as
\[2x^2-2x+1=0\]

Answer 4

or what you had, but it is usually easiest to work with a positive leading coefficient
they are the same equation though so it doesn't really matter
if you are luck it factors
if not, you have to use the quadratic formula

Answer 5

i dont think it can factor so i would i use quadratic formula?

Answer 6

actually there are no real number solutions to this equation

Answer 7

when you attempt the quadratic formula \(b^2-4ac=4-8=-4\) so the solutions are complex numbers
