If I'm correct, X=1/2. I'm almost completely sure
Answer:
1
Step-by-step explanation:
1 times anything equals the opisite number but in this case you are multiplying 1 by itself 999999999999 times and that equals 1
X2+7x-8=0
product=-8 times 1 = -8
sum= 7
{-1, 8}
x2-1x+8x-8=0
x(x-1)+8(x-1)=0
x+8=0 or X-1=0
x=-8
