Solve x2 = 12x - 15 by completing the square. Which is the solution set of the equation?

Novosadov [1.4K]

Answer:

(6-√21, 6+√21)

x^2 - 12x = -15

(x - 6)^2 - 36 = -15

(x - 6)^2 = 21

x - 6 = ± √21

x = 6 ± √21

The area of a rectangle with width × and length 7× is 7². what does the coefficient 7 mean in terms of the problem?

tatuchka [14]

The coefficient 7 means that the length is 7 times the width

<h3>How to interpret the coefficient?</h3>

The given parameters are:

Width = x

Length = 7x

Area = 7x^2

We have:

Length = 7x

Substitute Width = x in Length = 7x

Length = 7 * Width

This means that the length is 7 times the width
