Question

Find p if one zero of x^2+5x+p is -2. Also, find the other zero.

Answer 1

Hi Friend
________
Polynomial = f(x) x2+5x+p
let a and b its two zeros
a=-2 (given)
b= ?
p=?
put the value of a in polynomial
f(-2) 4-10+p=0
                 p=10-4
                 p= 6
also a+b= -b/a
        -2+b = -5/1
              b= -5+2
              b= -3
so the other zero is -3
