(7x-2)(7x+7)
=(7x)²+49x-14x-14
=7²x²+35x-14
=49x²+35x-14
(7x - 2)(7x + 7) = 7x * 7x + 7x * 7 - 2 * 7x - 2 * 7 = 49x² + 49x - 14x - 14 = 49x² + 35x - 14
The product of the expression ( 7 x − 2 ) ( 7 x + 7 ) is 49 x 2 + 35 x − 14 . This is determined using the distributive property where we multiply each term and combine like terms.
