Solve for x in the equation x2 + 2x + 1 = 17.
x=-11 15
x=-1+ v17
x=-2+25
x=-1v13

X=-1+ V17

Step-by-step explanation:

X^2+2x +1 =17

Write down the equation in the form of ax^2+bx +c=0, by taking 17 to the LHS

X^2 +2x +1 -17=0

X^2+2x-16=0

Using formulae method.

X= -b^2 + (√b^2-4ac)/2a

b=2, a=1 and c=-16

Slot in your values

You will have

X=-1+ V17

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

21
