Find the product (7x+1)(2x+7)

To find the product of (7x+1)(2x+7), we can use the distributive property:

(7x+1)(2x+7) = 7x(2x) + 7x(7) + 1(2x) + 1(7)

Simplifying this expression gives:

14x^2 + 49x + 2x + 7

Combining like terms:

14x^2 + 51x + 7

So, the product of (7x+1)(2x+7) is 14x^2 + 51x + 7.
