(x+9)4-64(x+9)2=0

(x + 9) 4 - 64 (x + 9) 2 = 0

x = - 9

Solution steps

(x + 9) \cdot 4 - 64 (x + 9) \cdot 2 = 0

Multiply the numbers:

64 \cdot 2 = 128

4 (x + 9) - 128 (x + 9) = 0

Add similar elements:

4 (x + 9) - 128 (x + 9) = - 124 (x + 9)

- 124 (x + 9) = 0

Divide both sides by

- 124

x + 9 = 0

Move

9

to the right side

x = - 9
