Notice that half of the coefficient of x is (1/2)(-4), or -2.
Then x^2 - 4x becomes
x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4. Then x = -2 plus or minus 2, and the two roots are 0 and -4.
Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.

Hello!!!
In this specific case the constant of proportionality is s (speed).
Step-by-step explanation:
The constant of proportionality stay "constant" (as the name suggests) in a certain case.
meaning, the speed itself remains constant at any given distance or time.
You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.
you can also switch up the formula:
d=st
t=d/s
s=d/t
i really hope this helps!!!!!
Answer:
(f+g)x= 2x²+5x-3
The domain x∈ Real number.
Step-by-step explanation:
Given that f(x) = 5x - 3 and g(x) = 2x²
(f+g)x = f(x) + g(x)
So, by using the given function
(f+g)x= (5x-3) + (2x²)= 2x²+5x-3
As the result, 2x²+5x-3, is a polynomial, so domain of the result is all the real numbers.
