Hello ,
40/21 = 21/21 + 19/21
40/21 = 1 + 19/21
40/21 = 1
40/21 = 21/21 + 19/21
40/21 = 1 + 19/21

Answer:
A
Step-by-step explanation:
Given
x² - x = 30
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- )x +
= 30 +
(x - )² =
Take the square root of both sides
x - = ±
= ±
Add to both sides
x = ±
, thus
x = -
= - 5
x = +
= 6
