Answer:
8*x^2
Step-by-step explanation:
Let x be the number
Expression is, 8*x^2
If we are to derive the equation that models the growth of the amoeba, we make use of the general form:
p = po k^t
where po is the initial population
k is the multiplicative rate of change
From the problem
3po = po k^(20)
k = 1.06
The equation is
p = 800 (1.06)^t

3 x^{2} + 8x +(-4) = 0
x = <u>-b + √ b² - 4ac</u>
2a
x = <u>-8 + √ 8² - 4(3)(-4)</u>
2(3)
x = <u>-8 + √64 - 48 </u>
6
x = -<u>8 + √16
</u> 6<u>
</u>x = -<u>8 + 4 </u> x = <u>-8 - 4</u>

</u>x = <u>-4 </u> x = <u>-12</u>
6 6
