Solve for x in the equation x squared +2x +1= 17

x = -1+✓17 or x = -1 -✓17

Step-by-step explanation:

x^2 + 2x + 1 = 17

Make the equation equal to 0 by taking away 17.

x^2 + 2x - 16 = 16

Put a, b and c into the quadratic formula.

a = 1 b = 2 c = -16

could

step-by-step explanation:

u send me a picture of ur work

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
