If `x+2\ ` is a factor of `x^2+m x+14 ,` then `m=` 7 (b) 2 (c) 9 (d) 14

If x+2\ is a factor of x^2+m x+14 , then m= (a) 7 (b) 2 (c) 9 (d) 14

(c) Factorize x^(2) -5x -14

If the arithmetic mean of 7,\ 8,\ x ,\ 11 ,\ 14 is x , then x= (a) 9 (b) 9.5 (c) 10 (d) 10.5

If the arithmetic mean of 7,\ 8,\ x ,\ 11 ,\ 14 is x , then x= (a) 9 (b) 9.5 (c) 10 (d) 10.5

Let's resolve into factors: 3x^2 + 14x + 8

If x+2 and x-1 are the factors of x^3+10 x^2+m x+n, then the values of m and n are respectively=? (a) 5 and -3 (b) 17 and -8 (c) 7 and -18 (d) 23 and -19

If x+1/x=2, then x^3+1/(x^3)=? (a)64 (b) 14 (c) 8 (d) 2
