What are the roots of 2x+6= -5/x?

Question

mww · Answer

As the root is not x = 0, multiply both sides by x and solve the quadratic you result in.

pythagoras123 · Answer

Even if the root was x=0, you are still allowed to multiply on both sides by x. It's dividing on both sides by x that you should avoid. 

$$2x ^{2}+6x=-5$$
$$2x ^{2}+6x+5= 0$$ 
$$x=?$$

luhvon · Answer

try one of these and see if it works  x =(2-√76)/6=(1-√ 19 )/3= -1.120  
2.  x =(2+√76)/6=(1+√ 19 )/3= 1.786

jhonyy9 · Answer

2x+6 = -5/x    interdiction of x that not can being equal by zero bc. than this fraction of -5/x will be undefined 

2x+6=-5/x  multiple both sides by x 

2x^2 +6x = -5

2x^2 +6x +5 = 0

D = 36 -40 = - 4 

x_1,2 = (-6 +/- sqrt(-4)/4 = (-6 +/- 2i)/4 = (-3+/- i)/2

hope this will help you
