If (x+2) and (x-1) are factors of the polynomial p(x)=x3+10x2+mx+n the

1.	If (x+2) and (x-1) are factors of the polynomial p(x)=x3+10x2+mx+n then (a) m=5,n=−3 (b) m=7,n=−18 (c) m=17,n=−8 (d) m=23,n=−19
Answer» If (x+2) and (x-1) are factors of the polynomial $p (x) = x^{3} + 10 x^{2} + m x + n$ then (a) $m = 5, n = - 3$ (b) $m = 7, n = - 18$ (c) $m = 17, n = - 8$ (d) $m = 23, n = - 19$
