First you need to find the area of the floor to know how much wood you need
Area=lengthxwidth, so A=40x14.5 which equals 580 square ft
With a floor that's 580 square ft and the boxes cover 18 Sq ft each then all you have to do is 580/18= 32.222 and because you can't buy .222 of a box you need to round up to 33 boxes

</span>30 + x thats yhur answer<span>
or
(3x2 + 1) • (x + 3)

Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
Step by step solution :<span>Equation at the end of step 1 :</span><span><span> (((3 • (x3)) + 32x2) + x) + 3
</span><span> Step 2 :</span></span><span>Equation at the end of step 2 :</span><span> ((3x3 + 32x2) + x) + 3
</span><span>Step 3 :</span>Checking for a perfect cube :
<span> 3.1 </span> <span> 3x3+9x2+x+3</span> is not a perfect cube
Trying to factor by pulling out :
<span> 3.2 </span> Factoring: <span> 3x3+9x2+x+3</span>
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 ....
<span><span> P Q P/Q F(P/Q) Divisor</span><span> -1 1 -1.00 4.00 </span><span> -1 3 -0.33 1.33 </span><span> 1 1 1.00 4.00 </span><span> 1 3 0.33 1.33 </span></span>
Polynomial Roots Calculator found no rational roots
Final result :<span> (3x2 + 1) • (x + 3) thats yhur answer</span>
