x-x^2-1<= 0

Solution

x - x^{2} - 1 \leq 0

Solution

True for all x

+1

Solution steps

x - x^{2} - 1 \leq 0

Complete the square

x - x^{2} - 1 : - (x - \frac{1}{2})^{2} - \frac{3}{4}

- (x - \frac{1}{2})^{2} - \frac{3}{4} \leq 0

Move

\frac{3}{4}

to the right side

- (x - \frac{1}{2})^{2} \leq \frac{3}{4}

Multiply both sides by

- 1

(x - \frac{1}{2})^{2} \geq - \frac{3}{4}

If n is even,

u^{n} \geq 0

for all
