User: solve for x. 9x^4 - 9x^2 + 2 = 0

Weegy: 9x^4-21x^2+10=0. Let k = x^2. Equation becomes: 9k^2 - 21k + 10 = 0. This equations factors out to be: (3k-5) * (3k-2) = 0 solve for k to get: k = 5/3 or k = 2/3 ...

a^3 - 2a^2 - 15a
= a(a^2 - 2a - 15)
= a(a + 3)(a - 5)

9x^4 - 9x^2 + 2 = 0
(3x^2 - 1)(3x^2 - 2) = 0
3x^2 - 1 = 0 or 3x^2 - 2 = 0
3x^2 = 1 or 3x^2 = 2
x^2 = 1/3 or x^2 = 2/3
x = ± sqrt3/3 or x = ± sqrt6/3

6/v=9/v-1/2
6/v - 9/v = -1/2
-3/v = -1/2
v = -3/( -1/2)
v= -3 *(-2)
v = 6

b^2 - 6b - 7=0
(b - 7)(b + 1) = 0
b = 7 or b = -1.
