First step of the equation is to simplify the equation 2a • b = a2 + b2 into 2 ab = a2 + b2. This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9. hence the answer to this problem is false. we can try another values to verify.

Answer:
40 quarts.
Step-by-step explanation:
Let x =quarts of the 50% solution
so, according to the question
the typical mixture equivalent equation will be like this

so the answer will be 40 quarts of 50% solution should be added.
