✔ 最佳答案
(12x + 7y)^2= (12x + 7y)(12x + 7y)
= 12x*12x + 7y*12x + 12x*7y + 7y*7y
= 144x^2 + 84xy + 84xy + 49y^2
= 144x^2 + 168xy + 49y^2

= (12x + 7y)²
= (12x + 7y)(12x + 7y)
= 144x² + 84xy + 84xy + 49y²
= 144x² + 168xy + 49y²
Answer: 144x² + 168xy + 49y²
= (12x + 7y)(12x + 7y)
= 144x² + 84xy + 84xy + 49y²
= 144x² + 168xy + 49y²
Answer: 144x² + 168xy + 49y²

To find this answer you take everything inside the parenthesis and come up with its square, 12 squared is 144x, and 7 squared is 69y, so the product would be 144x + 69y

(12x+7y)^2
=24x+14y
first multiply 2 with 12x and then +7y and just put the value.

Use (a+b)^2 fromula. Its 144x^2 + 168xy + 49y^2.

(12x + 7y) (12x + 7y)
Use the FOIL method:
144x^2 + 84xy + 84xy + 49y^2
