Question

factorise 2x power 4 + x cube minus 14 x square - 19 x minus 6​

Answer 1

Answer:

factor of 2x power 4 + x cube - 14 x square - 19 x - 6 is x = minus 1

Step-by-step explanation:

p(x) =   2x​4+ x3- 14x2 - 19x -6

    p(-1)  =    2.(-1)4+(-1)3-14.(-1)2-19x . -1-6

             =    2-1-14+19 - 6

             =  -21+21

             =   0

So (x+1) is a factor of p(x)= 2x​4+x3-14x2-19x -6​
