Mary - M
<span>Jim - J </span>
<span>Mary's ticket number is one less than Jim's ticket number. </span>
<span>J - 1 = M </span>
<span>The product of their numbers is 812 </span>
<span>M * J = 812 </span>
<span>plus first equation into 2nd </span>
<span>(J - 1) J = 812 </span>
<span>J^2 - J - 812 = 0 </span>
<span>(J - 29) (J + 28) = 0 </span>
<span>J = 29 or -28, 29 cuz you can't have negative for question. </span>
<span>J = 29 </span>
<span>plus 29 in first equation, </span>
<span>29 - 1 = M </span>
<span>28 = M </span>
<span>Mary's ticket number is 28 and Jim is 29</span>

Your image is cropped, so I can’t see the options to choose from but this would work too:
=> (x-2)(x-5)(x-7)
=> (x^2 -5x -2x +10)(x-7)
=> (x^2 -7x +10)(x-7)
=> (x^3 -21x^2 +10x -7x^2 + 49x -70)
=> x^3 -28x^2 + 59x -70
The following is true:
* the polynomial has a positive leading coefficient.
* the polynomial has a domain of x = (-oo, oo)
