Correct answer only ! thomas solved the equation by completing the square. x2 − 10x + 27 = 0 which equation shows one of the steps thomas could have taken to complete the square?

The correct step Thomas should have taken when using the completing the square method is x² − 10x + 25= -27 + 25

The standard form of a quadratic equation is given by:

ax² + bx + c = 0

There a is the coefficient of x², b is the coefficient of x and c is a constant.

The solution to the quadratic equation has to solutions.

Given the equation:

x² − 10x + 27 = 0

Solving using completing the square; first subtract 27 from both sides:

x² − 10x + 27 - 27 = 0 - 27

x² − 10x = -27

Add to both sides, the square of half of the coefficient of x (i.e. (-5)² = 25)

x² − 10x + 25= -27 + 25

(x - 5)² = -2

Therefore option C is the correct step, Thomas should have taken to complete the square
