How do you find the zeros, real and imaginary, of #y= -x^2-55x+37 # using the quadratic formula?
When I first came across the quadratic formula I decided that I really had to commit it to memory. So I wrote the thing out every time I answered a question of this type. I did it so often that it is really 'burnt' into my memory. This is one of those equations that is really worth remembering if you can.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The coefficient of The constant of Compare to standard form Setting Where Note that as we are applying plus or minus to the root it does not matter that the denominator is negative. So write it as positive just to make things tidy. The only whole number factors of 3173 are: 1 and 3173; 19 and 167. so we can not simplify the root any further than it is. Thus the exact answer is: Approximate answers are:

To find the zeros, real and imaginary, of ( y = -x^2 - 55x + 37 ) using the quadratic formula:
- Identify the coefficients of the quadratic equation: ( a = -1 ), ( b = -55 ), and ( c = 37 ).
- Substitute these coefficients into the quadratic formula: ( x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}} ).
- Calculate the discriminant: ( b^2 - 4ac ).
- Substitute the values of ( a ), ( b ), and ( c ) into the quadratic formula.
- Solve for ( x ) by using both the positive and negative square root of the discriminant.
- Express the solutions for ( x ) as real or imaginary numbers, depending on the value of the discriminant.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
