Solution

49 - x^{2} \geq 0

Solution

- 7 \leq x \leq 7

+1

Interval Notation

[- 7, 7]

Solution steps

49 - x^{2} \geq 0

Move

49

to the right side

- x^{2} \geq - 49

Multiply both sides by

- 1

x^{2} \leq 49

For

u^{n} \leq a

, if

n

is even then

- 49 \leq x \leq 49

49 = 7

- 7 \leq x \leq 7

Popular Examples

x*20000*(2153/315000)^2=29800

x \cdot 20000 \cdot (\frac{2153}{315000})^{2} = 29800

simplify (-12)^2 simplify

(- 12)^{2}

5(x+1)-7=3(x-1)+2x

5 (x + 1) - 7 = 3 (x - 1) + 2 x
