So
A.T.Q
x-3 and x+3
so to divide x4+x3-11x2-9x+18 we have to divide both the zeroes.
(x-3)(x+3)=x²-9(since (a-b)(a+b)=a²-b²)
so I have divide and I found that.
x²+x-2
x²+2x-x-2
x(x+2)-1(x+2)
(x-1)(x+2)
x= 1 ;x= (-2)
the zeroes of x⁴+x³-11x²-9x+18 is 3,(-3),(-2) and 1.
I hope you would like my answer and could be brainiest one.
