COMPLETING THE SQUARE (PROCESS):
Do a reverse factoring procedure to develop the following form of equation:
(t + a)^2 = b
where:
t = unknown variable
a = coefficient
b = coefficient
Then take square root of both sides to find value of unknown variable as follows:
t^2 + 10t = 75
(t^2 + 10t + 25) = 75 + 25
(t^2 + 5t + 5t + 25) = 100
(t + 5)(t + 5) = 100
(t + 5)^2 = 100
√(t + 5)^2 = √100
Two solutions exist:
+(t + 5) = 10
AND
-(t + 5) = 10
Thus:
t = 10 - 5 = 5
AND
t = -5 - 10 = -15
Answer:
t = 5
AND
t = -15
We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
1 Simplify a-3a+5a−3a+5 to -2a+5−2a+5
-2a+5-(-a+2b+3)−2a+5−(−a+2b+3)
2 Simplify brackets
-2a+5+a-2b-3−2a+5+a−2b−3
3 Gather like terms
(-2a+a)+5-2b-3(−2a+a)+5−2b−3
4 Simplify
-a+5-2b-3−a+5−2b−3
5 Simplify
-a-2b+2−a−2b+2
Answer:
2 Height ft and 6.75 length ft
Step-by-step explanation:
You just decrease it to 1:16
so, 34:108 is 2:6.75 to be about the same size as 1:16
Answer:

Step-by-step explanation:
Hey there!
Standard form is what this equation is in
Standard form is this: 
So order to complete the square, you need to take the
term out of the equation, divide it by two, and then square it
In this case, the
term is 8
We need to divide 8 by 2 ---> 4
Then square 4 ---> 16
So now you should add 16 to both sides

Now you can simplify the LHS

Now you subtract 16 from both sides

So this is as far as you can go since you cannot take the square root of a negative number
