Answer:
The expression in standard form will be [tex]x^4=2x^3-50x^2+115x-12[/tex]
Step-by-step explanation:
We have given polynomial [tex](x^2+7x-12)(x^2-9x+1)[/tex]
We have to write the given polynomial in standard form
For writing in standard form we have to first multiply then write in order
So after multiplication
[tex](x^2+7x-12)(x^2-9x+1)=x^4-9x^3+x^2+7x^3-63x^2+7x-12x^2+108x-12=x^4=2x^3-50x^2+115x-12[/tex]
So the expression in standard form will be [tex]x^4=2x^3-50x^2+115x-12[/tex]
