Question

2x + 9√(x) - 5 = 0 ; need help solving for x

Answer 1

its a quadratic; disguised

Answer 2

[√(x)]^2 = x

Answer 3

would i have to sqare everything else too?

Answer 4

no, its just the "form" that you are interested in; the structure of the variable is unimportant at the moment; solve it for:

√(x) = quadratic formula outputs

Answer 5

then determine x from that

Answer 6

alright thanks

Answer 7

if its right in me head i see it as:

2(5) = 10

10-1 = 9

(√(x)+10/2)(√(x)-1/2)

(√(x)+5)(√(x)-1/2)

√(x) = -5 or 1/2

[√(x) = -5 or 1/2] ^2

x = 25 or 1/4

Answer 8

the 25 might be a bad result that comes with the territory :)
