Hello here is a solution :
<span>x² − 8x − 4 = 0.
</span><span>quadratic equation ax²+bx+c = 0 when : a=1 and b= -8 and c = -4
discriminant : d = b²-4ac d= (-8)²-4(1)(-4) =64+16 =70
x= (-b-rot(d))/2a </span>x'= (-b+rot(d))/2a .......conrinu

Now, by filling value of y in 3(y+5), we get,



75 pints of juice : 5 containers
? pints of juice : 1 container
5 containers/5 = 1 container
75/5 = 15 pints of juices
The answer is 15 pints of juice
Answer is <span>x + 5y - 25 = 0
y - 5 = -1/5 (x-0)
y - 5 = -1/5x
-5y + 25 = x
x + 5y - 25 = 0</span>
