Expand the following using either the Binomial Theorem or Pascal’s Triangle. You must show your work for credit. (x - 3)^5
Rudiy27
I used bionomial expansion up to and including the term x^{3}

(-3 + x)^{5}

-3^{5} (1 +  -\frac{1}{3}x)  ^{5}

-243 (1 +  -\frac{1}{3}x)  ^{5}

n = 5
x = - \frac{1}{3}x


Binomial expansion:

1 + nx +  \frac{n(n-1) x^{2} }{2!} + \frac{n(n-1)(n-2) x^{3} }{3!}


Therefore:

1 + (5*-  \frac{1}{3}x) +  \frac{5(4) (- \frac{1}{3}x)^{2}  }{2} + \frac{5(4)(3) (- \frac{1}{3}x)^{3}  }{6}

=

1 -  \frac{5}{3} x +  \frac{10}{9} x^{2} -  \frac{10}{27}  x^{3} 



Multiply by -243

=

-243 + 405x - 270x^{2} +  90  x^{3}

Step-by-step explanation:

We are given the following in the question:

Length of rectangle:

x\text{ feet}

Width of rectangle:

(x-7)\text{ feet}

Perimeter of rectangle:

2\times \text{(Length + Width)}

Expressions to calculate perimeter

1. ~2((x) + (x - 7))\text{ feet}\\2.~2(2x-7)\text{ feet}\\3.~ 4x-14\text{ feet}

The attached image shows the image of the rectangle.
