From the problem we know that Hanna saves one-half of her paycheck each week, so she saves
![( \frac{1}{2})(160)= \frac{160}{2} =80](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B1%7D%7B2%7D%29%28160%29%3D%20%5Cfrac%7B160%7D%7B2%7D%20%3D80)
. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is
![80+50=130](https://tex.z-dn.net/?f=80%2B50%3D130)
.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>
![n](https://tex.z-dn.net/?f=n)
representing the number of weeks, we can model the situation as follows:

x=2
Answer:
and
Step-by-step explanation:
We have to solve the given equation - 2x² + 3x - 9 = 0
To solve the equation given above we have to factorize the left-hand side of the equation.
But it can not be factorized. So, use the Sridhar Achaya formula.
Therefore,
and
So,
and
{Where
}
Therefore, the solutions are imaginary numbers. (Answer)
Note: The Sridhar Acharya Formula gives if ax² + bx + c = 0, then the roots of the equation are
and
.
