Question

Polynomial of x2+ 3x+9

Answer 1

Answer:

x2+3x+3x+9

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

(x+3)(x+3)

Answer 2

HEYA!!

${x}^{2} + 3x + 9 = 0$

by using formula of D

$d = {b}^{2} - 4ac$

on comparing it with general equation

$a {x}^{2} + bx + c = 0$

we get

$d = {3}^{2} - 4 \times 1 \times 9$

$d = - 27$

since D has a negative value means ROOTS ARE IMAGINARY.
