@girlover first tell him the formula then solve his question then tell him answer

Find the product of (3x + 7y)(3x - 7y).
9x2 - 42xy + 49y2
9x2 + 42xy + 49y2
9x2 - 49y2
9x2 + 49y2

OpenStudy (haseeb96):
(a+b)^2 = a^2 + 2ab +b^2
so in the question
(x+7)^2 = x^2 + 2 (x) (7) + 7^2
=x^2 +14x +49
is the correct answer
OpenStudy (haseeb96):
(a+b)(a-b) = (a^2 - b^2 )
(3x + 7y)(3x -7y) = ( 9x^2 - 49y^2)
