Answer:
f(2) = -2
Step-by-step explanation:
plug in 2 to wherever x is in this statement:
f(2) = -2(2^2) - 2(2) + 10
f(2) = -2(4) - 4 + 10
f(2) = -8 - 4 + 10
f(2) = -2
Ok let's do this*pops knuckles*
let's add the first side
order of operations demands that we do multiplication first(P.E.M.D.A.S)
so
now we can add the 1 from
into our six
now we substract
now we have
now we focus on the
other side
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
now we have
(the three is from the original equation)
now we plug in our final numbers

What is it
I don't get it done
The answer is the answer is C and F.
This is found by inserting the equation above into the quadratic formula or -b plus or minus the square root of b^2 - 4ac over 2a.
With that, you find that the first number is a -3, which eliminates choices B and D.
Then, solving the 4ac portion, you find that inside the square root the number is 29, which gives you the last two answer choices.
Hope this helps!
