Question

Which three steps are correct when solving this quadratic equation by completing the square? X^2-10x=39

Answer 1

Step-by-step explanation:

Any answer that involes,

Step 1: Complete the Square

${x}^{2} - 10x = 39$

$( \frac{ - 10}{2} ) {}^{2} = 25$

${x}^{2} - 10x + 25 = 64$

Step 2: Turn the left side into a binomial

$(x - 5) {}^{2} = 64$

Step 3: Solve for x.

$x - 5 = + - 8$

$x - 5 = 8$

$x = 13$

OR

$x - 5 = - 8$

$x = - 3$

X=-3 or X=13
