You find two numbers which add to -2 and multiply to -3.
These numbers are -3 and 1 so your factors are (x - 3)(x + 1), assuming your expression does in fact represent zero.
x is thus either 3 or -1.
Check: 32 - (2 * 3) - 3 = 0? yes; -12 - (2 * -1) - 3 = 0? yes.

What is 2x squared plus x minus 3?
no posible answerImproved Answer:-2x2+x-3 = (2x+3(x-1) when factored
What is the simplified form of 3 over 2x minus 5 21 over 8 x squared minus 14x minus 15?
if you mean (3/(2x-5))(21/(8x2-14x-15)) you would get (63/( (2x-5)(4x+3)(2x-5) ) simplified more would be 63/ ( (2x-5)2(4x+3) )
What is x squared minus 7x plus 12 didved by x squared minus 2x minus 3?
(x2-7x+12)/(x2-2x-3)factor the numerator & denominator:(x-4)(x-3)/(x-3)(x-1)now reduce:(x-4)(x-3)/(x+1)(x-3)(x-4)/(x+1)
What is 3x squared minus 2x minus 5 equals 0?
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
How do you factor 2x squared minus 11x plus 15?
You have to experiment with different factors of 2, and different factors of 15. In this case, 2x2 - 11x + 15 = (2x - 5) (x - 3)
How do you solve 2x squared minus 5x minus 3?
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
How do you solve 4x squared minus 9?
4x2 - 9 = (2x + 3)(2x - 3)
How do you solve 5x minus 2 divided by x squared minus 2x minus 3?
The question contains an expression but not an equation. You cannot solve an expression.
How do you factor 2x squared minus 5x minus 3?
2x squared - 5x - 3 = (2x +1)(x -3)
