Complete the square for each expression. then factor the trinomial
x^2+8x

The value of x is or

Step-by-step explanation:

The expression is

To complete the square, the equation is of the form

The constant term c can be determined using,

Rewriting the expression and factoring the trinomial, we have,

Taking square root on both sides, we get,

Either,

 or

Thus, the value of x is   or

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
