or it could be ![- \frac{30x^2 + 5x -2}{5x}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B30x%5E2%20%2B%205x%20-2%7D%7B5x%7D)
Step-by-step explanation: Factor the numerator and denominator and cancel the common factors. OR Move the negative in front of the fraction.
Try both of them because they both could be right.

huh?
Step-by-step explanation:
The height that a ball reaches at a certain time t is given by the equation,
h = 2 - 15t + 5t²
We are asked to compute for the values of t that would allow the ball to reach a height of 7 meters.
Substitute the 7 to the equation,
7 = 2 - 15t + 5t²
Transposing,
5t² - 15t - 7 + 2 = 0
Simplifying,
5t² - 15t - 5 = 0
Divide the equation by 5,
t² - 3t - 1 = 0
The values of t can be calculated through the quadratic formula,
t = (-b +/- sqrt(b² - 4ac))/2a
Substituting,
t = (3 +/-sqrt (9 - 4(-1)) / 2(1)
t = 3.3 or t = -0.30
Since, we cannot have t as a negative number hence, our final answer is:
<em> t = 3.3 s</em>
