10 - 3 x^{2} > x^{2} + 10 - x

0 < x < \frac{1}{4}

Interval Notation

(0, \frac{1}{4})

Decimal Notation

0 < x < 0.25

Solution steps

10 - 3 x^{2} > x^{2} + 10 - x

Rewrite in standard form

- 4 x^{2} + x > 0

Factor

- 4 x^{2} + x : - x (4 x - 1)

- x (4 x - 1) > 0

Multiply both sides by

- 1

(reverse the inequality)

(- x (4 x - 1)) (- 1) < 0 \cdot (- 1)

Simplify

x (4 x - 1) < 0

Identify the intervals

0 < x < \frac{1}{4}
