Question

solve
w^(4)-12w^(2)-2=0
what is the solution
w=?

Answer 1

X^2 - 12X - 2 = 0

Answer 2

Can you do it?

Answer 3

course he can! after chlorophyll's step you need to ______. what goes in the blank?

Answer 4

(12 +/- SQRT(144+8))/2
(12 +/- SQRT(152))/2

(12 + 12.33)/2 = 12.165
(12 - 12.33)/2 = -0.165

Answer 5

That means:
w^2 = 12.165 Since the other root is negative and a square of a number can't be negative.
=> w = SQRT(12.165)
=> w = 3.488

Answer 6

solve the equation for u then replace w^2 with u

Answer 7

Look at my solution. That is what I did.
