Find the values of m and n if the polynomial 
and x + 2 as its factors.
x – 1 and x + 2 are factor of 
x = 1, x = -2
m+n-12=0
16+4m+2n-14= 0
4m+2n+2 =0
4m+2n= -2
2m+n= -1------(2)
Subtracting (2) from (1)
-m = 13
Put m = -13 in (1)
-13+n=12
N=12+13=25

If a + b + c = 15 and a2 + b2 + c2 = 83, find the value of a3 + b3 + c3 – 3abc
(a+b+c)2=a2+b2+c2+2(ab+bc+ca)
=152=83+2(ab+bc+ca)
2(ab+bc+ca)=225−83
(ab+bc+ca)=71
a3+b3+c3−3abc=(a+b+c)(a2+b2+c2−ab−bc−ca)
=15(83−71)
=180
