What is the zero in the quadratic function f(x)= 9x^2-54x-19?
Alex17521 [72]

Answer:

6.33... and 0.333...

Step-by-step explanation:

The quadratic formula is


x=\frac{-b+\sqrt{b^2-4ac} }{2a}.


It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions.  Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-54)+/-\sqrt{(-54)^2-4(9)(-19)} }{2(9)}\\x=\frac{54+/-\sqrt{2916+684} }{18}

We will now solve for the plus and the minus.

The plus,,,

x=\frac{54+\sqrt{3600}}{18}\\x=\frac{54+60}{18}\\x=\frac{114}{18}\\x=6.3

and the minus...

x=\frac{54-\sqrt{3600}}{18}\\x=\frac{54-60}{18}\\x=\frac{-6}{18}\\x=-0.333...

Gabriella is X years old her sister Felisha is 6 years older than she is their mother is twice as old is Felicia their aunt Tany
Makovka662 [10]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~

Let me lay down the Given, and than I'll solve the question...

<em>Felisha</em> is 6 years older than <em>Gabriella</em><em> - (y)</em>

<em>Their Mother</em> is 2 times older than <em>Felisha</em>

<em>Their Aunt (Tanya - [x] )</em> is X years older than <em>Their Mother</em>

<em /><u><em>We are solving for how old is Tanya? ...</em></u>

**I stated Gabriella with a y instead of an X so that the equation does not look confusing, feel free to replace my y with "<em /><em>Gabriella(X)</em>", when writing/typing your answer...

**When I use the variable <em>Z</em>, this is how many years Tanya is older than the Mother...


To find how many years Tanya is older than the Mother: Z = 2 * (6 + y)

Now... the answer is: X = (2 * (6 + y)) + Z

I stated it this way, because we have to add Felisha's and Gabriella's age first, and than your multiply that age <em>Total</em> by 2 to get the Mother's age...
