Solve 3(x 7) = 4x^213x 143x^213x^28

Question

Solve the equation

Solve for x

x_{1} = - \frac{6 21 \times 77334 4 ^{5}}{773344}, x_{2} = 0, x_{3} = \frac{6 21 \times 77334 4 ^{5}}{773344}

Alternative Form

x_{1} \approx - 0.17337, x_{2} = 0, x_{3} \approx 0.17337

Evaluate

3 (x \times 7) = 4 x^{2} \times 13 x \times 143 x^{2} \times 13 x^{2} \times 8

Remove the parentheses

3 x \times 7 = 4 x^{2} \times 13 x \times 143 x^{2} \times 13 x^{2} \times 8

Multiply the terms

21 x = 4 x^{2} \times 13 x \times 143 x^{2} \times 13 x^{2} \times 8

Multiply

More Steps

21 x = 773344 x^{7}

Add or subtract both sides

21 x - 773344 x^{7} = 0

Factor the expression

x (21 - 773344 x^{6}) = 0

Separate the equation into 2 possible cases

x = 0 21 - 773344 x^{6} = 0

Solve the equation

More Steps

x = 0 x = \frac{6 21 \times 77334 4 ^{5}}{773344} x = - \frac{6 21 \times 77334 4 ^{5}}{773344}

Solution

x_{1} = - \frac{6 21 \times 77334 4 ^{5}}{773344}, x_{2} = 0, x_{3} = \frac{6 21 \times 77334 4 ^{5}}{773344}

Alternative Form

x_{1} \approx - 0.17337, x_{2} = 0, x_{3} \approx 0.17337
