Solve the equation below by completing the square and then solving for x. x2 - 6x + 1 = 17

The expression for the square of a binomial is

Since your expression starts with

It means that , and so -6x must be twice the product of x and some number b. If you choose b = -3 you have

So, if you add 8 to both sides of your equation, you have

By choosing one sign at a time, we have the two solutions

the answer for this question is 38

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
