(2x^2-1)^2=36

解答

(2 x^{2} - 1)^{2} = 36

解答

x = \frac{7}{2}, x = - \frac{7}{2}, x = \frac{5}{2} i, x = - \frac{5}{2} i

求解步骤

(2 x^{2} - 1)^{2} = 36

对于

(g (x))^{2} = f (a)

解为

g (x) = f (a), - f (a)

解

2 x^{2} - 1 = 36 : x = \frac{7}{2}, x = - \frac{7}{2}

解

2 x^{2} - 1 = - 36 : x = \frac{5}{2} i, x = - \frac{5}{2} i

解为

x = \frac{7}{2}, x = - \frac{7}{2}, x = \frac{5}{2} i, x = - \frac{5}{2} i

(3y+18)(y^2-11y+30)=0

(3 y + 18) (y^{2} - 11 y + 30) = 0

solvefor y,x^2+y^3=c

so l v e f or y, x^{2} + y^{3} = c

2x^3+13x^2+16x+5=0

2 x^{3} + 13 x^{2} + 16 x + 5 = 0

r^{4} - 2 r^{2} + 1 = 0

x^{3} - 4 x - 2 = 1
