x2- 5x + 6 = (x - 3)(x - 2) When the first term of a trinomial is positive and the third term is negative,the signs in the factored form are opposite. That is, the factored form of x2- x - 12 would be of the form ...

通过这段代码,我们可以得到多项式x^2+3x+2的因式分解结果为(x+2)(x+1)。 除了factor命令,Matlab还提供了另外一种进行因式分解的命令——roots命令。roots命令可以根据多项式的根来进行因式分解。例如,我们有一个多项式表达式为x^2-5x+6,我们可以使用roots命令来进行因式分解。 ```matlab syms x polynomial = ...

2x+ 6 = 2 (x+ 3) Factors of 2x+ 6 are 1, 2, (x+ 3), (2x+ 6). So, the factor pairs of 2x+ 6 are (1, (2x+ 6)) and (2, (x+ 3)). Example 2: For the expression $x^ 2$ – x-2. $x^2$ – x – 2 = $x^2$ – 2 x + x – 2 = x (x – 2) + ...

20x = 2(5x)(2). To factor a perfect square trinomialform a binomial with the square root of the first term, the square root of the last term, and the sign of the middle term, and indicate the square of this binomial. Thus, 25x2+ 20x + 4 = (5x + 2)2 ...

Not all trinomials look like x2+5x+6x2+5x+6, where the coefficient in front of the x2x2 term is 1. In these cases, your first step should be to look for common factors for the three terms.TrinomialFactor out Common FactorFactored 2x2+10x+122x2+10x+12 2(x2+5x+6)2(x2+5x+6...
