Answer: x - 3
Step-by-step explanation:
Factor:
2x^2 - 18
1. Factor out 2: 2(x^2 - 9)
2.Factor x^2 - 9 into (x-3)(x+3): 2(x - 3)(x + 3)
*Notice that x^2 - a^2 can always be factored into (x-a)(x+a)
where a is a constant so in this case, a is 9 which is also 3^2
so x^2 - 9 can be factored into (x - 3)(x + 3)
x^2 - 2x - 3
1. Think what two numbers multiplied together is -3 and added together is 2
-> 3 and -1 since 3(-1) = -3 and 3+ (-1) = 2
2. Factor x^2 - 2x -3 into (x - 3)(x + 1)
Therefore, since both 2x^2 - 18 and x^2 - 2x -3 do not have another common factor besides x - 3, x - 3 is the HCF of 2x^2 - 18 and x^2 - 2x -3.
<span>I believe you are missing the rest of your question...
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

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>
