factor

x^{4} - 10 x^{2} = - 9

x = - 1, x = 1, x = - 3, x = 3

Solution steps

x^{4} - 10 x^{2} = - 9

Move

9

to the left side

x^{4} - 10 x^{2} + 9 = 0

Factor

x^{4} - 10 x^{2} + 9 : (x + 1) (x - 1) (x + 3) (x - 3)

(x + 1) (x - 1) (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x - 1 = 0 or x + 3 = 0 or x - 3 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x - 1 = 0 : x = 1

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

x = - 1, x = 1, x = - 3, x = 3

\frac{3}{4}

15 a - 12 a^{2}

x^{2} - 9 x = 10

x, 5^{x} = 55

x, \frac{5}{( x - 5 )} = \frac{x}{( x - 5 )} - \frac{5}{4}
