Question

Find the sum of sum and product of roots of the Quadratic equation (x +1)(x + 2) = 0.

Answer 1

Answer:

-1 is the answer

Step-by-step explanation:

Let the roots be 'a' and 'b', then,

from the equation, we get, x= -1 or x= -2

OR a= -1 and b= -2

Now, a+b= -1+(-2) = -1-2 = -3

ab= (-1)(-2) = +2

Now, sum of sum and product of the zeroes

= 2-3 = -1 Answer
