- \frac{x}{25 - x ^{2}} = 4

x = - \frac{20}{17}

Decimal Notation

x = - 4.85071 \dots

Solution steps

- \frac{x}{25 - x ^{2}} = 4

Multiply both sides by

25 - x^{2}

- \frac{x}{25 - x ^{2}} 25 - x^{2} = 4 25 - x^{2}

Simplify

- x = 4 25 - x^{2}

Square both sides:

x^{2} = 400 - 16 x^{2}

x^{2} = 400 - 16 x^{2}

Solve

x^{2} = 400 - 16 x^{2} : x = \frac{20}{17}, x = - \frac{20}{17}

x = \frac{20}{17}, x = - \frac{20}{17}

Verify Solutions:

x = \frac{20}{17}

False

, x = - \frac{20}{17}

True

The solution is

x = - \frac{20}{17}

3 x + 5 x^{2} + 11 - 5 = 0

x, x + y = 10

- 72.2 = 16.7 + a^{0.015}

x + 2 = 3 - x

8 = x x
