Question

What is x in the equation: 6x + 20 = -2x^2 ?

Answer 1

5,-2

Answer 2

my bad. I ment 17, not 20

Answer 3

-17(+/-) sqrt(17^2-4(6)(2))
can you do that

Answer 4

and all over 2(2)

Answer 5

-17 +/- sqrt(241).. the rest I'm not sure about

Answer 6

sorry I have led you incorrectly

Answer 7

I will do the problem and show the steps,

Answer 8

\[6x + 20 = -2x^2 \implies 2x^2+6x+20=0 \implies no~real~solution\]

Answer 9

I say no real solution since the determinant is negative.

Answer 10

yep
so
-6+/- sqrt(36-5(17)(2))/4
x= (-3-5i)/2
x=(-3+5i)/2

Answer 11

i ment 17, not 20 @AnimalAin

Answer 12

OK, but my answer is still the same...

Answer 13

That would be the discriminant, not the determinant.... foolishness....

Answer 14

medal please
