-x^2+6x-9>= 0

Solution

- x^{2} + 6 x - 9 \geq 0

Solution

x = 3

+1

Interval Notation

x = 3

Solution steps

- x^{2} + 6 x - 9 \geq 0

Factor

- x^{2} + 6 x - 9 : - (x - 3)^{2}

- (x - 3)^{2} \geq 0

Multiply both sides by

- 1

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

For

u^{n} \leq 0

, if

n

is even then

u = 0

x - 3 = 0

Move

3

to the right side

x = 3
