Question

Two negative integers are 8 units apart on the number line and have a product of 308.

Which equation could be used to determine x, the smaller negative integer?

x2 + 8x – 308 = 0
x2 – 8x + 308 = 0
x2 + 8x + 308 = 0
x2 − 8x − 308 = 0

Answer 1

X²-8x+308

Explanation:

two negative integers -x and -x= +x²

8units apart=-8x

all equals 308

X²-8x=308

bring everything to the LHS

X²-8x-308=0
