A ^ - 3x of x ^ - 3x plus 1 = x + 2 of 30 to solve the equation

A ^ - 3x of x ^ - 3x plus 1 = x + 2 of 30 to solve the equation


(x^2-3x+1)/(x^2-4)=30/(x+2)
(x^2-3x+1)/(x-2)=30
x^2-3x+1=30x-60
x^2-33x+61=0
x=(33±√1333)/2



X ^ 4 + 3x = 2! Find X
X ^ 4 is the fourth power of X


Let f (x) = x ^ 4 + 3x-2, obtain f '(x) = 4x ^ 3 + 3,
Then there is x0
The minimum value of F (x) is f (1 / 4 under the third root)



How to solve x minus 2 = 3x of 4


How to solve x minus 2 = 3x of 4
x/ 4 = 2
x = 8
