(\frac{3}{4 x + 1})^{3} - (x + 2)^{3} + (0.25 x + 1)^{3} = 0

x \approx 0.11867 \dots, x \approx - 1.63653 \dots

Solution steps

(\frac{3}{4 x + 1})^{3} - (x + 2)^{3} + (0.25 x + 1)^{3} = 0

Simplify

(\frac{3}{4 x + 1})^{3} : \frac{27}{( 4 x + 1 ) ^{3}}

\frac{27}{( 4 x + 1 ) ^{3}} - (x + 2)^{3} + (0.25 x + 1)^{3} = 0

Multiply both sides by

(4 x + 1)^{3}

27 - (x + 2)^{3} (4 x + 1)^{3} + (0.25 x + 1)^{3} (4 x + 1)^{3} = 0

Solve

27 - (x + 2)^{3} (4 x + 1)^{3} + (0.25 x + 1)^{3} (4 x + 1)^{3} = 0 : x \approx 0.11867 \dots, x \approx - 1.63653 \dots

x \approx 0.11867 \dots, x \approx - 1.63653 \dots

Verify Solutions

Find undefined (singularity) points:

x = - \frac{1}{4}

Combine undefined points with solutions:

x \approx 0.11867 \dots, x \approx - 1.63653 \dots

\frac{3}{4 x ^{2} - x - 1} = 0

x, \frac{( d ^{2} \cdot y )}{( d \cdot x ^{2} )} + y = 0

x, g^{- 1} (2) g = \frac{20}{x} + 1

\frac{133}{4 \cdot ( x - \frac{13}{55} ) - 10 x} = 2 x - 1

\frac{( x - 2 )}{( x + 3 )} = 2
