Answer:

Therefore the two negative integers are - 22, - 14.

Step-by-step explanation:

Given that, two negative number are are 8 units apart.

Let x be a negative integer one of them.

Then the another integer be (x+8)

Given that the product of them is 308.

According to the problem,

x(x+8)=308

\Rightarrow x^2+8x=308

\Rightarrow x^2+22x-14x-308=0

\Rightarrow x(x+22)-14(x+22)=0

\Rightarrow (x+22)(x-14)=0

\Rightarrow x=-22,14

Since x is a negative integer.

∴x = - 22.

Then another integer is =( - 22+8) = -14

Therefore the two negative integers are - 22, - 14.

USPshnik [31]
1 and 1/2x+3/4x=5/8
combine x's
1 and 1/2x=4/4x+2/4x=6/4x
6/4x+3/4x=5/8=9/4x
9/4x=5/8
multiply both sides by 8
18x=5
x=5/18

x=5/18 or aprox 0.277777777777
