we are given

$(5x + 1)(5x - 1)$

we can distribute it

$5x*5x-1*5x+1*5x-1*1$

$25x^2-5x+5x-1$

now, we can simplify it

$25x^2-1$ ...............Answer

Answer:

a)2x-3y

b)4(9a-4)

Step-by-step explanation:

we want to expand the following expression:

$\displaystyle - \frac{1}{4} ( - 8x + 12y)$

well to do so we consider distributive property thus distribute:

$\displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)$

reduce fraction which yields:

$\displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)$

simplify Parentheses:

$\displaystyle \boxed{ 2x - 3y}$

in the expression there's a common factor of 4 therefore factor it out:

$\displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}$
