<h3><u>Answer</u> :</h3>
Given equation : 3x² - 4 = 2x
We have to find discriminant of the equation
⭆ 3x² - 4 = 2x
⭆ 3x² - 2x - 4 = 0
By comparing this equation with ax²+bx+c, we get
- a = 3
- b = -2
- c = -4
Discriminant (D) = b² - 4ac
⭆ D = (-2)² - 4(3)(-4)
⭆ D = 4 + 48
⭆<u> D = 52</u>

What information does the zero of the equation 6 = –16x2 + 24x + 1 represent?
In this case
</span><span> 0=-16x2+24x+1-6 .............> -16x2 +24x -5 = 0
</span><span>
If we graph the equation, we can see that the solutions are
x1 = 0.25 and x2 = 1.25
These points represent the moment when the ball is 6 ft above the ground
(0.25 seconds after being thrown and 1.25 seconds after being thrown)</span>
