Hi mate!!!
Hi mate!!!Here is ur answer:-
here, it is given that (x+3) is a factor of x²+7x+k =0
So, zero of (x+3) must be the value of x in the given equation, i.e (-3) would be the value of x in the given equation
x²+7x+k = 0
So, putting value of x i.e, (-3) in the given equation, we get
x²+7x+k = 0
(-3)²+7(-3)+k = 0
(9)+(-21)+k = 0
9 - 21 + k = 0
-12 + k = 0
k = 12
therefore, value of k = 12
hence, option a) is correct.
