Mathematics

Kay [80]3 years ago

Answer:

(2x +5y)(2x − 5y)  = {4x^{2}  - 25y^{2}

Step-by-step explanation:

(2x +5y)(2x − 5y) is the given equation.

Now, the <u>ALGEBRAIC IDENTITY</u> states that:

(a+ b)(a-b) = a^{2}  - b^{2}

Here, comparing a = 2x  and b = 5y,

we get (2x +5y)(2x − 5y)  = (2x)^{2}  - (5y)^{2}

on further solving the right side, we get

(2x +5y)(2x − 5y)  = {4x^{2}  - 25y^{2}
