4x^(2) + 28xy + 49y^(2) -> (2x)^(2) + 28xy + (7y)^2 Split into brackets ( 2x + 7y)(2x + 7y) If you applyuFOIL you will find toy come to '28xy'. The clue to this problem is to note that '4' ^ '49' are both squared numbers.

4x2+28x+49 = (2x+7)(2x+7) when factored
4x2+49 First multiply then addition. 8+49 =57 Answer is 57.
(2x-7)(2x-7) = area 4x2-28x+49 = area
(4x + 7)(16x2 - 28x + 49)
49 + 49 + 49 + 49 + 49 = 245 OR 49*5=245
That doesn't look quite right. As written, that's 4x + 61, which doesn't factor. If you meant 4x2 + 49x + 12, the answer is (4x + 1)(x + 12)
