Q.

(2 x+5)(2 x-5)=

Identify Formula: Identify the formula to use for multiplying two binomials that are conjugates. $\newline$ We use the difference of squares formula, which is $(a+b)(a-b) = a^2 - b^2$ .
Substitute Values: Substitute the values of $a$ and $b$ into the formula. $\newline$ Here, $a = 2x$ and $b = 5$ . So, $(2x+5)(2x-5) = (2x)^2 - 5^2$ .
Calculate Squares: Calculate the squares of $2x$ and $5$ . $(2x)^2 = 4x^2$ and $5^2 = 25$ . So, $(2x+5)(2x-5) = 4x^2 - 25$ .
