The coefficient of quadratic term is 1
x²-5x+6=(x-2)(x-3)
x²-5x-6=(x+1)(x-6)
x²-5x+4=(x-1)(x-4)
The coefficient of quadratic term is not 1
Please answer 2x square - 5x + 3
(2x-3)(x-1)
2 -3
1 -1
How to judge quadratic trinomial can be decomposed by cross multiplication factor
It's better to give a few examples
ax^2+bx+c=0
The necessary condition for decomposition is that B ^ 2-4ac ≥ 0 and is a square number, such as 1,4,9,16,25, etc
