Answer:

Standard form of [tex](x-9)(3x-7) + (3x^{2} - 5x+2)[/tex] [tex]=6x^{2}  - 39x + 65[/tex]

Step-by-step explanation:

Here, the given expression is [tex](x-9)(3x-7) + (3x^{2} - 5x+2)[/tex]

Now, simplifying the above expression in parts, we get

[tex](x-9)(3x-7) = 3x^{2}  - 7x -27x + 63 = 3x^{2}  - 34x + 63[/tex]

hence, combining both parts:

[tex](x-9)(3x-7) + (3x^{2} - 5x+2)[/tex][tex]=(3x^{2}   -34x +63) + (3x^{2} - 5x+2)[/tex]

= [tex]6x^{2}  - 39x + 65[/tex]

The above expression is of the STANDARD FORM: [tex]ax^{2}  +bx + c[/tex]

Hence, the standard form of [tex](x-9)(3x-7) + (3x^{2} - 5x+2)[/tex] [tex]=6x^{2}  - 39x + 65[/tex]
