Solve 1/2(d^4)=d-1

Evaluate

\frac{1}{2} d^{4} = d - 1

Move the expression to the left side

\frac{1}{2} d^{4} - (d - 1) = 0

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

\frac{1}{2} d^{4} - d + 1 = 0

Factor the expression

\frac{1}{2} (d^{4} - 2 d + 2) = 0

Divide both sides

d^{4} - 2 d + 2 = 0

Calculate

d \approx 0.873409 + 0.436319 i d \approx 0.873409 - 0.436319 i d \approx - 0.873409 + 1.155557 i d \approx - 0.873409 - 1.155557 i

Solution

d_{1} \approx - 0.873409 - 1.155557 i, d_{2} \approx - 0.873409 + 1.155557 i, d_{3} \approx 0.873409 - 0.436319 i, d_{4} \approx 0.873409 + 0.436319 i

1/2(d^4)=d 1
