\left(\sqrt{14c-14}\right)^{2}=\left(\sqrt{4c+6}\right)^{2}
Square both sides of the equation.
14c-14=\left(\sqrt{4c+6}\right)^{2}
Calculate \sqrt{14c-14} to the power of 2 and get 14c-14.
14c-14=4c+6
Calculate \sqrt{4c+6} to the power of 2 and get 4c+6.
14c-14-4c=6
Subtract 4c from both sides.
10c-14=6
Combine 14c and -4c to get 10c.
10c=6+14
Add 14 to both sides.
10c=20
Add 6 and 14 to get 20.
c=\frac{20}{10}
Divide both sides by 10.
c=2
Divide 20 by 10 to get 2.
\sqrt{14\times 2-14}=\sqrt{4\times 2+6}
Substitute 2 for c in the equation \sqrt{14c-14}=\sqrt{4c+6}.
14^{\frac{1}{2}}=14^{\frac{1}{2}}
Simplify. The value c=2 satisfies the equation.
c=2
Equation \sqrt{14c-14}=\sqrt{4c+6} has a unique solution.
