(2x + 1) (x + 3) = 2x2 + 7x + 3
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
if its 3x3 - 2x + 1 then its a cubic trinomial
(3x - 1) + 7 = (7x - 2x) + x3x - 1 + 7 = 7x - 2x + x3x + 6 = 6x6 = 3xx = 6/3 = 2
5x2+ 7x + 2 = (x + 1)(5x + 2).
(2x + 1) (x + 3) = 2x2 + 7x + 3
(2x + 1)(x + 3) are the factors.
[ x3 + 3x2 + 2x ] is a trinomial. It's factors are [ x, (x + 1), (x + 2) ] .
The factors of 6x2+7x-5 are (3x+5) and (2x-1).
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
7x-1=2x+5 7x-2x=5+1 5x=6 x=6/5=1.2
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
if its 3x3 - 2x + 1 then its a cubic trinomial
(3x - 4)(x - 1)
(3x - 1) + 7 = (7x - 2x) + x3x - 1 + 7 = 7x - 2x + x3x + 6 = 6x6 = 3xx = 6/3 = 2
5x2+ 7x + 2 = (x + 1)(5x + 2).
