Solve x^4 = (4x - 5)2

Evaluate

x^{4} = (4 x - 5) \times 2

Multiply the terms

x^{4} = 2 (4 x - 5)

Expand the expression

More Steps

x^{4} = 8 x - 10

Move the expression to the left side

x^{4} - (8 x - 10) = 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

x^{4} - 8 x + 10 = 0

Calculate

x \approx 1.323757 + 0.491407 i x \approx 1.323757 - 0.491407 i x \approx - 1.323757 + 1.806428 i x \approx - 1.323757 - 1.806428 i

Solution

x_{1} \approx - 1.323757 - 1.806428 i, x_{2} \approx - 1.323757 + 1.806428 i, x_{3} \approx 1.323757 - 0.491407 i, x_{4} \approx 1.323757 + 0.491407 i
