Question

Zeros ofthe polynomial x2 + 5x + 6​

Answer 1

Answer:

x2+5x+6

x2+3x+2x+6

x(x+3)+2(x+3)

(x+3) (x+2)

hence zerores are -2 and -3.

Answer 2

Step-by-step explanation:

let p(x) = x2 + 5x + 6

To find the zeros of p(x) we put

p(x)=0

x2 + 5x + 6 = 0

x2 + 2x + 3x + 6= 0

x(x+2) + 3(x + 6)=0

(x+2)(x+3)=0

either x + 2 =0 or x + 3 = 0

either x = -2 or x = -3

Hence the zeros of the given quadratic polynomial are -2 and -3
