Which of the following is a valid conclusion for the problem x2 + 6x + 8 = 0?

x = -2 or x = -4

Step-by-step explanation:

Step 1 : Middle term break

x^2 + 6x + 8 = 0

x^2 + 4x + 2x + 8 = 0 (4+2 is equal to six and 4x2 is equal to  8)

x(x + 4) + 2(x +4)

(x+2) (x+4)

x= -2 or x= -4

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
