Root both sides of the equation

x+3= plus or minus root 7

Subtract 3 from both sides.

x_{1} = \sqrt{7} -3\\\\ x_{2}= - \sqrt{7} -3

The attractive electric force between point charges q and -2q has a magnitude of 2.2 N when the separation
swat32

Answer:

The Magnitude of charge = q = 15.47 micro coulomb  

Step-by-step explanation:

The attractive force between two points q and - 2 q = F = 2.2 Newton

The separation between two charges = 1.4 meters

Now from Coulomb's law = F = (k \frac{q1 q2}{r^{2}})  where k= 9 \times 10^{9} \frac{N m^{2}}{c^{2}}

So , 2.2 = 9 \times 10^{9} ( (\frac{(q) ( - 2q)}{1.4^{2}})

So , q ² = (\frac{0.479 \times 10^{-9}}{-2})

      For charge magnitude

   I.e q ² = 2.395 \times 10^{-10}

 so, q =  1.547 \times 10^{-5}

      q = 15.47 \times 10^{-6} c

Or,  q = 15.47 micro coulomb

Hence  the Magnitude of charge = q = 15.47 micro coulomb   Answer

Don't give me the answer just explain where I messed up.
ira [324]

Answer:

9x^2 -2x+8

Step-by-step explanation:

( 9x^2 -5x) - ( -3x -8)

Distribute the minus sign

( 9x^2 -5x) +3x +8

Combine like terms

9x^2 -2x+8

The x^2 should be positive and you have it as negative
