Question

obtain all other zeroes of the polynomial x4+2x3-13x2-38x-24 and if two
of its zeroes are -1 and -2 ​

Answer 1

Answer:

-3and 4

Step-by-step explanation:

(x+1) (x+2) = x²+3x+2

x⁴+2x³-13x²-38x-24 divide it by x²+3x+2

we get x²-x-12

then factories it

and we get

(x+3)(x-4)

x= -3 , 4
