2x2 + 3x + 1 = (x + 1)(2x + 1)
2x2-3x-5 = (2x-5)(x+1) when factored
If you mean: 2xsquared+3x+1 then it is (2x+1)(x+1) when factored
If: 2x2-3x+1 = 0 Then: x = 1 or x = 1/2
2x2+5x+3 = (2x+3)(x+1) when factored
No.
2x2-3x-5 = (2x-5)(x+1) when factored and multiply out the brackets to check that your answer is correct
2x2+5x+3 = (2x+3)(x+1) when factored
6x2+5x+1 = (3x+1)(2x+1) when factored
9x^2 +6 +1 is (3x+1)(3x+1) when factored
No. You'd have to use the ABC-formula
This expression could be reordered as 1 + 3x + 2x2.
It is a quadratic expression and can be factored into: (3x+1)(x+2)
