Question

Which statement describes the first step to solve the equation by completing the square?

4x^2 + 16x = 20

Multiply both sides of the equation by 1/4

Add 64 to each side of the equation

Add 8 to each side of the equation

Multiply both sides of the equation by 1/8

Answer 1

Multiply both sides of the equation by 1/4.

Explanation:

Correct answer for k12.

Answer 2

see explanation

Explanation:

Given

4x² + 16x = 20

To complete the square we require the coefficient of the x² term to be 1

Divide all terms on both sides by 4 or by the listed statements

multiply both sides of the equation by
`(1)/(4)` to obtain

x² + 4x = 5

The process of completing the square can now be performed.
