Answer:

[tex]x^{2} -3x-28[/tex]

Step-by-step explanation:

To find this equation in standard form, first, write it in factored form. This looks like [tex]y=(x+4)(x-7)[/tex]. Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.

  1. Following the FOIL method, you should multiply the first terms in each binomial, [tex]x*x[/tex], which equals [tex]x^{2}[/tex].
  2. Then, the outside terms, [tex]x*-7[/tex]. This equals [tex]-7x[/tex].
  3. Next, the inside terms, [tex]4*x[/tex][tex]=4x[/tex].
  4. Finally, the last terms, [tex]4*-7[/tex], this equals [tex]-28[/tex].

Then, add all of the terms together [tex]x^{2} + -7x+4x+-28[/tex]. To get the standard form, combine like terms, this comes out to [tex]x^{2} -3x-28[/tex].
