Question

The area of an American flag is given by the polynomial 3x ^ 2 - 2x + 12xy - 8y . Factor by grouping to find the possible dimensions of the rectangle in factored form .

Answer 1

(3x-2)(x+4y)

Explanation:

3x^2-2x+12xy-8y

3x^2+12xy=3x(x+4y)

-2x-8y=-2(x+4y)

3x^2-2x+12xy-8y=3x(x+4y)-2(x+4y)

(3x-2)(x+4y)
