6x2 + 14x -12 = (3x - 2) (2x + 6). There they are.
7 + 24 ÷ (6x2) =7 + 24 ÷ 12 = 7 + 2 = 9
6x^2 + 5x + 1 = (3x +1) (2x + 1)
(4y)2 = 16y2
5x2 - 20xy + 10y2 = 5(x2 - 4xy + 2y2) which cannot be simplified into rational factors.
9+6x2=21
(x + 2y)(3x + 8y)
The expression has no rational factors.
6x2=12 2x-28=?
6x2 + 10x = 2x(3x + 5)
(2x - 3y)(2x - 7y)
2*2*5*x*y
2y(2y - 1)(2y - 3)
2y(2y - 1)(2y - 3)
5xy (2x - 3y + 4 )
No.
