A) 85 acres with 1.02 x 10⁶ plants
b) 100 acres with 1.7 x 10⁷ plants
c) 110 acres with 1.9 x 10⁶ plants
d) 205 acres with 3.4 x 10⁵ plants
a) 1.02 x 10⁶ = 1,020,000 ÷ 85 acres = 12000 per acre
b) 1.7 x 10⁷ = 17,000,000 ÷ 100 acres = 170,000 per acre
c) 1.9 x 10⁶ = 1,900,000 ÷ 110 acres = 17,272.73 per acre
d) 3.4 x 10⁵ = 340,000 ÷ 205 acres = 1658.54 per acre
Among the choices, Letter C. 110 acres with 1.9 x 10⁶ plants has the density of approximately 17000 plants per acre. Its actual density is 17,272.73 plants per acre.
I don't like dividing polynomials so I'm going to set x=1 and try them out.
(1-2-14+3)/4 = -3
Of the choices, only D gives -3 when x=1
~~~~~~~~~~~~~~~~~~~~~~
That's as much test-taking as math. If we were to divide
x^2 - 5x + 1
-------------------------------
x + 3 | x^3 - 2x^2 - 14x + 3
x^3 + 3x^2
-5x^2 - 14x
5x^2 + 15x
x + 3
x + 3
More work, still choice D

Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: x+3
Group 2: <span> 3x3+9x2</span>
Pull out from each group separately :
Group 1: (x+3) • (1)
Group 2: <span> (x+3) • (3x2)</span>
-------------------
Add up the two groups :
<span> (x+3) • </span><span> (3x2+1)</span>
Which is the desired factorization
Polynomial Roots Calculator :
<span> 3.3 </span> Find roots (zeroes) of : <span> F(x) = 3x2+1</span>
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 3 and the Trailing Constant is <span> 1.
</span>The factor(s) are:
of the Leading Coefficient : <span> 1,3
</span>of the Trailing Constant : <span> 1
</span>Let us test ....
