I'm stuck on a few problems and was hoping I could get some help.
x^2=4-2x
the answer key says x=-1 plus or minus √5 but I have not been able to come to this.
Also,
2x^(2/3)-5x^(1/3)=3
hi drewm
for the first one,move all of the terms to one side.then use the quadratic formula to get x.
for the second one use the substitution t=x^(1/3),then move all of the terms to one side,use the quadratic formula to get t and calculate x from t.
