x^2-30x+150<= 0

x^{2} - 30 x + 150 \leq 0

- 53 + 15 \leq x \leq 53 + 15

Solution steps

x^{2} - 30 x + 150 \leq 0

Complete the square

x^{2} - 30 x + 150 : (x - 15)^{2} - 75

(x - 15)^{2} - 75 \leq 0

Move

75

to the right side

(x - 15)^{2} \leq 75

For

u^{n} \leq a

, if

n

is even then

- 75 \leq x - 15 \leq 75

a \leq u \leq b

then

a \leq u and u \leq b

- 75 \leq x - 15 and x - 15 \leq 75

- 75 \leq x - 15 : x \geq - 53 + 15

x - 15 \leq 75 : x \leq 53 + 15

Combine the intervals

x \geq - 53 + 15 and x \leq 53 + 15

Merge Overlapping Intervals

- 53 + 15 \leq x \leq 53 + 15
