7(y + 4)
(6x + 5)(6x + 5) or (6x + 5)2
(x + 1)(x - 2)(x + 5)
(x^2 + 1)(x^2 - 4x + 13)
No
35x2 - 38x + 8
21x3-35x2+14x = 7x(3x2-5x+2)
-(5x + 3)(7x - 2)
(7x - 5)(5x - 2)
(5x - 3)(7x + 9)
5x(x^4+7x+4)
It is: 4x -34x^2 -21 simplified
12n2 plus 8n?
6a squared-8ab+2a factor completely and check mentally
10a * (a + 2)
(x + 9)(x + 4)
(x+3)(x+3)
