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

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
