Step-by-step explanation:

Given:

We need to find the roots of quadratic equation using quadratic formula.

For quadratic expression

Quadratic formula

In Given expression the values of a,b,c are;

We will first find by substituting the given values;

=

Now Substituting the above value in quadratic formula we get;

Now we will find 2 different roots as;

Hence the 2 roots are .

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

is should be y = 5x
