<em>What is the value of c in the quadratic </em>?
Before starting to solve, you should notice something - the
quadratic is not in its standard form!
We can easily fix it by adding on both sides:-
We can switch the order of 28 and -11x:-
Now, the quadratic is in its standard form, so we can get down to
finding the value of "c".
Remember, the standard form of a quadratic looks like so:-
Now we can just write our <u>quadratic</u> here:-
Now, can you see what the value of "c" is?
An easy way to <u>remember</u> "c" in quadratics is:-
The "c" in quadratics is the constant.
Henceforth, we conclude that the value of "c" in the given quadratic is:-
