Find the real zeros of the function, state their multiplicities if it is a number other than 1.
-$f ( x ) = x ^ { 2 } + 10 x + 21$
A) $x = - \sqrt { 21 } , x = \sqrt { 21 }$
B) $x = - 7 , x = - 3$
C) $x = - 7 , x = 28$
D) $x = 3 , x = 7$

Question

Quizplus · Accepted Answer

The quadratic equation $x^2 + 10x + 21$ can be factored into $(x + 7)(x + 3) = 0$, giving the real zeros $x = -7$ and $x = -3$, each with multiplicity 1.
