Given a quadratic equation

1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.
In our case the coefficient of x is 10, so we write 10 as 2*5
2. then we write +

and -

to the expression:



Answer:
Answer:
a = 1, b = 2, c = 3
Step-by-step explanation:

A = 1/2 b h
5 = 1/2 (5) h
10 = 5h
h = 10/5
h = 2
answer
2
Just do 6 x 0.2 to reverse the division
So the answer is 1.2
