5x(6x + 7y + 8)
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.
(9,6)
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
(y + 5) (y + 2)
5x(6x + 7y + 8)
(4x - 7y)(4x + 7y)
(7y + 2)(7y - 2)
This is a difference of two sqaures. 49y2 - z2 = (7y - z)(7y + z)
16x2+56xy+49y2
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.
The GCF is 7.

If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
8y + 7y = 15ySo [ 8y + 9 + 7y ] = 15y + 9If you want to get fancy and factor that expression, it's 3(5y + 3) .
