Question

If a+b=6, ab=7, what is the value of a^2b+ab^2

Answer 1

Answer:

the correct answer to this question is 42

explanation

Answer 2

Given:

• a+b=6

=> a= 6-b

• ab=7

= a²b + ab²

= (6-b)b + 7²

= 6b - b² + 49

= -b²+6b +49

b² - 6b - 49 = 0 (taking out minus common)

then factorize using quadratic formula (D = b²-4ac)
