-2x^2+x-1>= 0

Solution

- 2 x^{2} + x - 1 \geq 0

Solution

No Solution

Solution steps

- 2 x^{2} + x - 1 \geq 0

Complete the square

- 2 x^{2} + x - 1 : - 2 (x - \frac{1}{4})^{2} - \frac{7}{8}

- 2 (x - \frac{1}{4})^{2} - \frac{7}{8} \geq 0

Move

\frac{7}{8}

to the right side

- 2 (x - \frac{1}{4})^{2} \geq \frac{7}{8}

Multiply both sides by

- 1

2 (x - \frac{1}{4})^{2} \leq - \frac{7}{8}

Divide both sides by

2

(x - \frac{1}{4})^{2} \leq - \frac{7}{16}

If n is even,
