its this right?

Joe348:

\[-5+\sqrt{5^2-4(-1)(-8)}\]

Joe348:

then devided by -2?

Joe348:

thats right right?

carmelle:

yes, that is correct, now keep on going.. can you do the rest?

Joe348:

it wont let me put it in on the calculator it says goto or quit

carmelle:

what do you mean?

Joe348:

like.. when i type the square root of the numbers on the calculator it says error

carmelle:

ok, so you might want to do the calculation by hand because sometimes calculators have errors

Joe348:

yeah no im good lmao

carmelle:

its easy... what is 5^2 equal to?

Joe348:

25

Joe348:

sneak them answers B) lol jp

Joe348:

waittt its -7 right?

carmelle:

ok, what is \[4 \times -1 \times -8\] equal to

Joe348:

i got -7 total

Joe348:

so \[-5+7/2(-1)\]

carmelle:

yes it would be -7, but you must remember, because the discriminant is a negative number (-7) you can stop right there. you cannot move on- the solution to this is: `No real solutions` understood? That is why your calculator kept on saying error btw^

Joe348:

oh lol and yes i got it thank you

carmelle:
