To solve this problem you must apply the proccedure shown below:
1. You have the following quadratic equation, which is given in the problem above:
<span>2y^2+6y-8=0
2. So, to solve it, you can use the quadratic formula, which is:
y=(-b</span><span>±</span>√(b²-4ac))/2a
<span>
a=2
b=6
c=-8
3. When you susbtitute these values into the formula, you obtain:
y1=-4
y2=1</span>
6+(6+1)=total number of puppies
6= Kate's puppies
(6+1)= Jim's puppies
related equation could be -18b = -18
simplifying the other side would be to divide both sides by -18.
b = 1
