2 a - 5 = \frac{4}{a}

a = \frac{5 + 57}{4}, a = \frac{5 - 57}{4}

Solution steps

2 a - 5 = \frac{4}{a}

Multiply both sides by

a

2 a^{2} - 5 a = 4

Solve

2 a^{2} - 5 a = 4 : a = \frac{5 + 57}{4}, a = \frac{5 - 57}{4}

a = \frac{5 + 57}{4}, a = \frac{5 - 57}{4}

Verify Solutions

Find undefined (singularity) points:

a = 0

Combine undefined points with solutions:

a = \frac{5 + 57}{4}, a = \frac{5 - 57}{4}
