@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

how about this one?

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)
