how to factorise 2x^2+5x-3
Jawaban Terbaik: You start by factoring the 2x^2: (2x + .....) (x + .....) Then you factor the -3 into -1 and 3, and put it in the parentheses: (2x - 1) (x + 3) Now multiply it out to check: 2x^2 -x +6x - 3 = 2x^2 + 5x - 3 So, the answer is (2x - 1) (x + 3).aporkan Penyalahgunaan. What you have to realize is that now instead of factoring x^2 into x and x, you're now factoring 2x^2 into 2x and x. If you look at your outside terms, 2x^2 only has 2 possible factors (2x and x), and 3 only has 2 possible factors (3 and 1).
