Complete the square to transform the quadratic equation into the form (x - p) 2 = q. x2 - 8x - 10 = 18

(x-4) ² = 44

Step-by-step explanation:

To complete the square, take the middle term - 8x and divide the coefficient in 2 and square it. Here it is - 8/2 = - 4. - 4² = 16. Add 16 to both sides.

x² - 8x - 10 = 18

x² - 8x + 16 - 10 = 18 + 16

(x-4) ² - 10 = 34

(x-4) ² = 44

(x - 4) 2 = 44
