Question

For a quadratic polynomial x²+5x+6 then sum of zeros of polynomial​

Answer 1

Answer:

The zeros are -2, -3

Step-by-step explanation:

x² + 5x + 6 = 0

x² + 2x + 3x + 6 = 0

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

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

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

x + 2 = 0    ;      x + 3 =0

x =-2          ;       x =  -3

As general equation: x² + S x + P

S = Sum , P = product

So, the sum of polynomial is 5
