Answer:

x = - 2 or x = - 8

Step-by-step explanation:

Given

2(x² + 10x) = - 32 ( divide both sides by 2 )

x² + 10x = - 16

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = - 16 + 25

(x + 5)² = 9 ( take the square root of both sides )

x + 5 = ± √(9) = ± 3 ( subtract 5 from both sides )

x = - 5 ± 3, thus

x = - 5 + 3 = - 2 or x = - 5 - 3 = - 8

What is the difference between 3/5 and 2/10

Answers

The answer is 2/5. This is because if you simplify 2/10 it becomes 1/5. Then, you do 3/5 subtracted by 1/5 and that is how you get to 2/5.
