-4k^{2}=-5+5
Add 5 to both sides.
-4k^{2}=0
Add -5 and 5 to get 0.
k^{2}=0
Divide both sides by -4. Zero divided by any non-zero number gives zero.
k=0 k=0
Take the square root of both sides of the equation.
k=0
The equation is now solved. Solutions are the same.
-4k^{2}-5+5=0
Add 5 to both sides.
-4k^{2}=0
Add -5 and 5 to get 0.
k^{2}=0
Divide both sides by -4. Zero divided by any non-zero number gives zero.
k=\frac{0±\sqrt{0^{2}}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 0 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
k=\frac{0±0}{2}
Take the square root of 0^{2}.
k=0
Divide 0 by 2.
