Question

Simplify the product in standard form (2r-3)(2r+3)

Answer 1

4r2−9.

Explanation:

The product of the two binomials (2r−3) and (2r+3) can be simplified using the difference of squares formula, which states that for any two terms a and b, the expression a2−b2 can be rewritten as (a−b)(a+b).

Here, a=2r and b=3. So, the product (2r−3)(2r+3) simplifies to:

(2r)2−32=4r2−9

So, the simplified form of (2r−3)(2r+3) is 4r2−9.

Answer 2

4r

Explanation:

(2r-3)(2r+3) is the same as (2r-3)+(2r+3) muiltyply the r and the 3s then subtract the 3s cancel out so 4r
