Ok the answer is 5x2 is 10 and then minus 2-4 is 2 and then 4x+2 is 6
Can you show me how you got that?
So 6 is in the box
When you have a quadratic with 1 as the coefficient of the x^2 term, to complete the square, take half of the x-term coefficient, and square it.
Perfect math student
x^2 - 4x doe have a 1 as the coefficient of the x^2 term. The coefficient of the x term is -4. Take half of -4. Then square that.
Okay, thanks guys!
You have to do 2-4 equal 2
@noliveiraa What did you get?
Our medals please
so it would be -4?
I got 2
and i gave the medals already @spid
It's not spid it's spiderman
No. The complete the square term is always positive. Half of -4 is -2 -2 squared is 4. The answer is 4.
What ever man bye
Okay, so i am confused the answer 6 or not
I'm going to cry
6 is incorrect. The complete the square term has to be a perfect square. 6 is not a perfect square, so 6 cannot possibly be correct.
He don't know nothing
Math man good luck
So then it is 4 because 4 is a perfect square, and i believe mathstudent55
I don't got it
@noliveiraa Now you got it. 4 is the answer.
Hey my medal
I'm reporting u
You gave me the wrong answer and did not help me
I did to
Well 4 was right
In wasting my time
