Answer:
The value of b is 60.
Step-by-step explanation:
In order to find the middle term, we have to create a perfect square using the square roots of each end term. The square root of 25x^2 is 5x. The square root of 36 is 6. So we take those and distribute. Then we will get the middle term.
(5x + 6)^2
(5x + 6)(5x + 6)
25x^2 + 30x + 30x + 36
25x^2 + 60x + 36
