2x^2-6x+3<0

2 x^{2} - 6 x + 3 < 0

\frac{- 3 + 3}{2} < x < \frac{3 + 3}{2}

Solution steps

2 x^{2} - 6 x + 3 < 0

Complete the square

2 x^{2} - 6 x + 3 : 2 (x - \frac{3}{2})^{2} - \frac{3}{2}

2 (x - \frac{3}{2})^{2} - \frac{3}{2} < 0

Move

\frac{3}{2}

to the right side

2 (x - \frac{3}{2})^{2} < \frac{3}{2}

Divide both sides by

2

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

For

u^{n} < a

, if

n

is even then

- \frac{3}{4} < x - \frac{3}{2} < \frac{3}{4}

a < u < b

then

a < u and u < b

- \frac{3}{4} < x - \frac{3}{2} and x - \frac{3}{2} < \frac{3}{4}

- \frac{3}{4} < x - \frac{3}{2} : x > \frac{- 3 + 3}{2}

x - \frac{3}{2} < \frac{3}{4} : x < \frac{3 + 3}{2}

Combine the intervals

x > \frac{- 3 + 3}{2} and x < \frac{3 + 3}{2}
