Find the values of a and b such that x^2 + 3x + 4 = (x + a)^2 + b

URGENT!

*silly answers will be reported

a = 1.5

b = 1.75

Step-by-step explanation:

First, we need to solve and replace the result in the initial equation as:

Then, this equality apply only if the coefficient of is equal in both sides and the constant is equal in both sides.

It means that we have two equations:

So, using the first equation and solving for a, we get:

Finally, replacing the value of a in the second equation and solving for b, we get:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
