Question

I have to solve this equation by making the appropriate substitution. Does anyone know how to work this problem? x+3x^1/2-10=0

Answer 1

try substitute y=x^1/2 so x=y^2

Answer 2

Ok I see what you are trying to do but does that mean I don't combine the x"s?

Answer 3

nothing to combine there as u cannot combine x and x^1/2

use the substitution n solve for u first

Answer 4

Can you show me how you would set up the problem using those substitutions?

Answer 5

y=x^1/2
y^2=x
put in the original eqn...
