Answer:
Step-by-step explanation:
12x12=144
19x12/2=228/2=114
114+144=258
I think it is the third one
try c
The answer is C
By using the quadratic formula, you get
a=1
b=5
c=7
so, when you substitute, you get:
-5±√5²-4(2)(7)
____________
2(1)
The next step is solving the square root and multiplying
