(3x - 2)(x + 8)
x^2 + 10x + 16 = (x + 8)(x + 2)
(x+1)(x+8)
Pull out the common factor of 2 ... 2(y^2+6y-16) Then just factor (y^2+6y-16) ... (y-2)(y+8)
5x(6x + 7y + 8)
(3x - 2)(x + 8)
x^2 + 10x + 16 = (x + 8)(x + 2)
(x+1)(x+8)
It is: 8n(5n+8)
Pull out the common factor of 2 ... 2(y^2+6y-16) Then just factor (y^2+6y-16) ... (y-2)(y+8)
5x(6x + 7y + 8)
(b + 8)(b + 4)
(2x - 1)(5x + 8)
(b + 8)(b - 1)
You don't! There are no common factors.
2(x^2 - 8)
x2 + 6x + 8 =(x + 2)(x +4)
