Question

What are the zeroes of f(x)= x^2 +5x+6?
A- x= -2, -3
B- x=2,3
C- x= -2,3
D- = 2,-3

Answer 1

Well we need to find the factors of the polynomial

Answer 2

hint:
we have to solve the subsequent quadratic equation:
\[\Large {x^2} + 5x + 6 = 0\]

Answer 3

please apply the standard formula:
\[\Large \begin{gathered}
x = \frac{{ - b \pm \sqrt {{b^2} - 4 \times a \times c} }}{{2 \times a}} \hfill \\
\\
a = 1,\;b = 5,\;c = 6 \hfill \\
\end{gathered} \]

Answer 4

we can either use use the quadratic equation, complete the square or any other ways of solving polynomials.

Answer 5

I'm honestly so lost @deeezzzzz
