Solve 6x-123x 8 x-6=180

Question

Solve the equation(The real numbers system)

x \in / R

Alternative Form

No real solution

Show Solution

Solve using the quadratic formula in the complex numbers system

Solve by completing the square in the complex numbers system

Solve using the PQ formula in the complex numbers system

x_{1} = \frac{1}{328} - \frac{7 415}{328} i, x_{2} = \frac{1}{328} + \frac{7 415}{328} i

Alternative Form

x_{1} \approx 0.003 \dot{0} 487 \dot{8} - 0.434759 i, x_{2} \approx 0.003 \dot{0} 487 \dot{8} + 0.434759 i

Evaluate

6 x - 123 x \times 8 x - 6 = 180

Multiply

More Steps

6 x - 984 x^{2} - 6 = 180

Move the expression to the left side

6 x - 984 x^{2} - 186 = 0

Rewrite in standard form

- 984 x^{2} + 6 x - 186 = 0

Multiply both sides

984 x^{2} - 6 x + 186 = 0

Substitute a= 984,b= - 6 and c= 186 into the quadratic formula x = \frac{- b \pm b ^{2} - 4 a c}{2 a}

x = \frac{6 \pm ( - 6 ) ^{2} - 4 \times 984 \times 186}{2 \times 984}

Simplify the expression

x = \frac{6 \pm ( - 6 ) ^{2} - 4 \times 984 \times 186}{1968}

Simplify the expression

More Steps

x = \frac{6 \pm - 732060}{1968}

Simplify the radical expression

More Steps

x = \frac{6 \pm 42 415 \times i}{1968}

Separate the equation into 2 possible cases

x = \frac{6 + 42 415 \times i}{1968} x = \frac{6 - 42 415 \times i}{1968}

Simplify the expression

More Steps

x = \frac{1}{328} + \frac{7 415}{328} i x = \frac{6 - 42 415 \times i}{1968}

Simplify the expression

More Steps

x = \frac{1}{328} + \frac{7 415}{328} i x = \frac{1}{328} - \frac{7 415}{328} i

Solution

x_{1} = \frac{1}{328} - \frac{7 415}{328} i, x_{2} = \frac{1}{328} + \frac{7 415}{328} i

Alternative Form

x_{1} \approx 0.003 \dot{0} 487 \dot{8} - 0.434759 i, x_{2} \approx 0.003 \dot{0} 487 \dot{8} + 0.434759 i
