Answer:
(x - 6)² - 17
Step-by-step explanation:
Given
x² - 12x + 19
Using the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² - 12x
= x² + 2(- 6)x + 36 - 36 + 19
= (x - 6)² - 17
X=-3
multiply the number three times by the other number.
It is C
c=4
subtract 50-18= 32
then subtract 12c-4c= 8c
8c=32
divide 8c by 32 which gives you
