Answer:

After subtracting (x^2+3x-7)-(3x^2-5x+3) we get

-2x^2+8x-10 expression in standard form

Step-by-step explanation:

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

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

negative sign changed the signs

[tex](x^{2} -3x^{2} ) +(3x+5x)+(-7-3)\\-2x^{2} +8x+(-10)\\\\\negative\,sign\,will\, change\, the\, signs\, again\\-2x^{2} +8x-10[/tex]

So -2x^2+8x-10 is the expression in standard form
