Question

Expand (5a+6b)²

please tell me soon ​

Answer 1

Answer:

(5a+6b)^2 = 25a^2 + 36b^2 + 60ab.

Step-by-step explanation:

As we know that,

(a+b)^2 = a^2 + b^2 +2ab.

so,

(5a+6b)^2 = (5a)^2 + (6b)^2 + (2×5a×6b).

= 25a^2 + 36b^2 + 60ab.

HOPE IT WILL BE HELPFUL!!..

Answer 2

Answer:

=25a²+60ab+36b²

Step-by-step explanation:

=(5a+6b)(5a+6b)

=5a(5a+6b)+6b(5a+6b)

=25a²+30ab+30ab+36b²

=25a²+60ab+36b²
