x^2-3x+4>0

Solution

x^{2} - 3 x + 4 > 0

Solution

True for all x

+1

Interval Notation

(- \infty, \infty)

Solution steps

x^{2} - 3 x + 4 > 0

Complete the square

x^{2} - 3 x + 4 : (x - \frac{3}{2})^{2} + \frac{7}{4}

(x - \frac{3}{2})^{2} + \frac{7}{4} > 0

Move

\frac{7}{4}

to the right side

(x - \frac{3}{2})^{2} > - \frac{7}{4}

If n is even,

u^{n} \geq 0

for all

u

True for all x

Popular Examples

((x+2))/((x-1))<4

\frac{( x + 2 )}{( x - 1 )} < 4

((7-2k))/((4(-k)))<= 1

\frac{( 7 - 2 k )}{( 4 ( - k ) )} \leq 1

((2(x-4)))/(((x-1)(x-7)))<= 1/((x-2))

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

(x-1)(x-2)*(x-3)^2>0

(x - 1) (x - 2) \cdot (x - 3)^{2} > 0

1/((x+1))> 1/((x-2))

\frac{1}{( x + 1 )} > \frac{1}{( x - 2 )}
