2x squared - 5x - 3 = (2x +1)(x -3)
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
5x(x - 2)
2x2 - 5x = 3 ∴ 2x2 - 5x - 3 = 0 ∴ 2x2 + x - 6x - 3 = 0 ∴ x(2x + 1) - 3(2x + 1) = 0 ∴ (x - 3)(2x + 1) = 0 ∴ x ∈ {-0.5, 3 }
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)
The question contains an expression but not an equation. You cannot solve an expression.
-x2+2x
7x2 -4x -5x2 +2x = 2x2 -2x
(4+x) (2x-3)
(2x - 7)(x + 1)
(x - 1)(5x + 7)
5x lolzz 8)
(2x-3)(x-1)
(2x - 1)(x + 3)
After long division, (2x2-5x+5)/(x-2) = 2x-1+3/(x-2).
(2x - 1)(5x + 8)
