Solve 2(x^2)^2-5=93

Evaluate

2 (x^{2})^{2} - 5 = 93

Simplify

More Steps

2 x^{4} - 5 = 93

Move the constant to the right-hand side and change its sign

2 x^{4} = 93 + 5

Add the numbers

2 x^{4} = 98

Divide both sides

\frac{2 x ^{4}}{2} = \frac{98}{2}

Divide the numbers

x^{4} = \frac{98}{2}

Divide the numbers

More Steps

x^{4} = 49

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 449

Simplify the expression

More Steps

x = \pm 7

Separate the equation into 2 possible cases

x = 7 x = - 7

Solution

x_{1} = - 7, x_{2} = 7

Alternative Form

x_{1} \approx - 2.645751, x_{2} \approx 2.645751
