Hey
x^2 + 5x + 6 = 0
x^2 + 3x + 2x + 6 = 0
x(x+3)+2(x+3) = 0
(x+2)(x+3) = 0
x + 2 = 0
x = -2
x + 3 = 0
x = -3

Answer:
-2 and -3
Step-by-step explanation:
p(x) = x^2 + 5x + 6
By Middle term splitting we get,
x^2 + 3x + 2x + 6 = 0
x(x + 3) + 2(x + 3)
(x + 3) (x + 2)
(x + 3)
x = - 3
(x + 2)
x = - 2
★ Verification
⇒ p(-3) = (-3)^2 + 5(-3) + 6
p(-3) = 9 - 15 + 6
0
⇒p(-2) = (-2)^2 + 5(-2) + 6
p(-2) = 4 - 10 + 6
0
★ Therefore the zeroes of polynomial p(×) = x^2+ 5x + 6 are -2 and -3.
