Question

Explain how to solve 4x 2- 5x = 16 by completing the square. What are the solutions?

Answer 1

`x = (16)/(3)`

Explanation:

Solve the equations:

`4x \: 2 - 5x = 16`

Multiply the monomals:

`8x - 5x = 16`

Combine like terms:

`3x = 16`

Divide both sides of the equation by the coefficient of variable:

`x = 16 / 3`

Calculate:

`x = (16)/(3)`
