Question

Find the value of (2x + 5)2.

Answer it please ​

Answer 1

Step-by-step explanation:

Solution:

(2x + 5)2

We know that (p + q)2 = p2 + q2 +2pq

Here, p = 2x , q = 5

(2x + 5)2 = (2x)2 + 52 + 2 × 2x × 5

= 4x2 + 25 + 20x

Answer 2

2x = 5/2

then we would divide both sides of the equation by two to find the value of x that makes the original equation true.

x = 5/4.
