Question 30238: Which equation below is the quadratic equation in standard form that results when you substitute u=x^-2 into the equation x^-4 -32+ 4x^-2 ?
POssible Answers:
(a) 1/u^2 - 4/u - 32=0
(b) u^2-4u-32=0
(c) u^4-4u^2-32=0
(d) u^-2 -4u +32=0
(e) 1/ u^2 + 4/u -32 = 0
Please be specific in which is the correct answer. Thanks! Answer by mukhopadhyay(490) (Show Source):
You can put this solution on YOUR website! x^-4 -32+ 4x^-2 =0
u=x^-2
=>u^2+4u-32=0
Standard form of quadratic equation is ax^2+bx+c=0
None of the given equations is correct. Check your problem please.
