Solution steps

x^{2} - 7 > 0

Move

7

to the right side

x^{2} > 7

For

u^{n} > a

, if

n

is even then

x < - 7 or x > 7

Popular Examples

x^{2} = 5 x + 24

6 x + 5 = 1 + 2 (3 x + 2)

expand (a+b+c)^2 expand

(a + b + c)^{2}

((7b-14))/b <= 5

\frac{( 7 b - 14 )}{b} \leq 5

simplify (3x^2y^3-5a^2x^4)/(-3x^2)simplify

\frac{3 x ^{2} y ^{3} - 5 a ^{2} x ^{4}}{- 3 x ^{2}}
