Question

X^2 - 51 = 14x
1) Rewrite the equation by completing the square.
Your equation should look like (x + c)^2 = d or (x-c)^2 =d

Answer 1

Step-by-step explanation:

x² - 14x - 51 = 0

(x² - 17x) + (3x - 51) = 0

x(x - 17) + 3(x - 17) = 0

(x + 3) (x - 17) = 0

x + 3 = 0 eq1

x = 0 - 3

x = -3

x - 17 = 0 eq1

x = 0 + 17

x = 17
