Question

the product of the two polynimals is (7x+2) and(7x-2) is
$(7x + 2)and(7 \times - 2)$
​

Answer 1

Answer:

49$x^{2}$-4

Step-by-step explanation:

We know that (a+b)* (a-b)= $a^{2}$-$b^{2}$

In the question a= 7x

                         b= 2

Therefore, (7x+2)*(7x-2)= $(7x)^{2}$- $2^{2}$= 49$x^{2}$-4
