Answer:

30

Step-by-step explanation:

Given

ab=5

a²+b²=25

So

(a+b)²=a²+ab+b²

=a²+b²+ab

=25+5

=30

Answer:

(a + b)² = 35

Step-by-step explanation:

Note the expansion of (a + b)²

(a + b)² = a² + b² + 2ab ← substitute given values

            = 25 + 2(5)

            = 25 + 10

            = 35
