Answer:
12, - 7
Step-by-step explanation:
Correct question:- find the sum and product of Roots of quadratic equation
(1) x² + 7x + 12=0
To find sum and product:- find Roots first
Solution:-
=> x² + 7x + 12 = 0
=> x² + 4x + 3x + 12 = 0
=> x(x + 4) + 3(x + 4) = 0
=> (x + 4)(x + 3) = 0
=> x + 4 = 0 | x + 3 = 0
=> x = - 4, - 3
Sum = - 3 - 4 = - 7
Product = 12
