Problem Solving (PS) | Re: If the sum of two numbers is 19 and their product is 88, what is the

\(a + b = 19\)
\(ab = 88\)

Or,\(a = 19 - b\)

So, We have :\((19 - b)b = 88\)

Or,\(b^2 - 19b + 88 = 0\)

Or,\(b^2 -11b - 8b + 88 = 0\)

Or,\(b(b - 11) -8(b - 11) = 0\)

So,\(b = 11\) and\(8\)

Thus, difference of the numbers is 3, answer must be (B)
