Solve for k
k=-5x\left(5x+2\right)
Solve for x (complex solution)
x=\frac{\sqrt{1-k}-1}{5}
x=\frac{-\sqrt{1-k}-1}{5}
Solve for x
x=\frac{\sqrt{1-k}-1}{5}
x=\frac{-\sqrt{1-k}-1}{5}\text{, }k\leq 1

10x+k=-25x^{2}
Subtract 25x^{2} from both sides. Anything subtracted from zero gives its negation.
k=-25x^{2}-10x
Subtract 10x from both sides.
