Question

Expand : a
J1) (2a² + 5)²​

Answer 1

$4a {}^{2} + 25 + 20a$

Answer 2

Hey mate here's the solution to your question:-

(2a² + 5)²

We know that,

(a+b)²

= a² + b² + 2ab

Therefore, here,

a=2a² and b=5

Therefore, putting the values of a and b in (a + b)²:-

(2a²+5)²

=(2a²)² + (5)² + 2(2a²)(5)

=4a⁴ + 25 +20a²

Hence, the answer is:- 4a⁴ + 20a² + 25

Hope it's helpful.
