Question

Solve the equation p^2 - 4p = 10 by completing the square

Answer 1

Explanation:

p² - 4p = 10

add the square of half of the "b" value to each side of the equation

b/2 = -4/2 = -2

-2² = 4

p² - 4p + 4 = 10 + 4

p² - 4p + 4 = 14

(p - 2)(p - 2) = 14

(p - 2)² = 14

p - 2 = √14

p = 2 + √14
