Question

One of the zeroes of, y = x2 + 5x + 6 is .​

Answer 1

Answer:

One of the zeros of y is x = -2, or x = -3.

Step-by-step explanation:

For zeroes, we equate the expression to zero.

$x^2 + 5x + 6 = 0$

$=>x^2 + 2x + 3x + 6 = 0$

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

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

Either x + 2 = 0, i.e. x = -2

or x + 3 = 0, i.e. x = -3

Therefore, one of the zeros of y is x = -2, or x = -3.
