I hope this helps you

x^2/2+12x/2+10/2=0

x^2+12x+10=0

ax^2+bx+c=0

disctirminant =b^2-4ac

x1,2=-b (-,+) square root of disctirminant /2a

a=1 b=12 c=10

disctirminant = 12^2-4.1.10=144-40=104

x1= -12+square root of 104/2

x2= -12- square root of 104/2

Answer:

Hello first one is 4.

Second one is 8

Step-by-step explanation:

First one is f(0). It means you should put zero in the place of x

0 is less than 5 so you should put zero in x+4=f(x)

For the second one do like the first one.

I hope you understand
