5x-1+2= 5x+1
That expression is the square of (5x + 1), so both of its factors are the same.
6x^2 + 5x + 1 = (3x +1) (2x + 1)
It is: 8-5x simplified
(5x + 1)2 = 25x2 + 10x + 1
It is 5xy + 5x.
-15x2+5x=-5x(3x-1)
5(x2 + x + 1)
7x + 2
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
6x2+5x+1 = (3x+1)(2x+1) when factored
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
