2x2 + 5x + 3 Notice the first term, which can be rewritten as 2x times x. With this in mind, you can write the equation as...
(2x + a)(x + b)
...where -a and -b are the answers.
You know that a times b is equal to 3.
With a little trial and error, you will find:
2x2 + 5x + 3 = (2x + 3)(x + 1)
2x squared - 5x - 3 = (2x +1)(x -3)
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
(5x-10)(x+3)
5x(x - 2)
(2x + 1)(x + 2)
(x - 1)(5x + 7)
(2x-3)(x-1)
2x squared - 5x - 3 = (2x +1)(x -3)

(2x - 1)(5x + 8)
-x2+2x
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
(2x+3)/(10x2+21x+9)Factor the quadratic expression in the denominator:(2x+3)/(5x+3)(2x+3)which becomes:1/(5x+3) or (5x+3)-1
2x2 + 5x = x*(2x + 5)
If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)
2x2+5x+3 = (2x+3)(x+1) when factored
