Question

from a quadratic equations whose roots are -1and -2

Answer 1

Roots are -1 & -2.

Sum of roots = -1 + (-2)
= -1 -2
= -3

Product of roots = -1 × -2
= 2

Equation is:-
x^2 - (sum of roots)x + (product of roots)

= x^2 - (-3)x + (2)
= x^2 + 3x +2

So,
F(x) => x^2 + 3x + 2 = 0

Hope it helps.
