Question

What are the zeroes of f(x) = x2 + 5x + 6?

x = −2, −3
x = 2, 3
x = −2, 3
x = 2, −3

Answer 1

Here is your answer

a) x=-2, -3

REASON :
$f(x)= {x}^{2}+5x+6$

= ${x}^{2}+2x+3x+6$

= $x(x+2)+3(x+2)$

= $(x+2)(x+3)$

To find zeroes

f(x)= 0

So,

(x+2)(x+3)=0

$x=-2 or x=-3$

HOPE IT IS USEFUL

Answer 2

Answer:

x = −2, 3 is the answer.
