Question

Subtract
2x^2+5x-7 from 7x^ 3-5x+3​

Answer 1

Answer:

Given that:-

Subtract 2x^2+5x-7 from 7x^3-5x+3

=>(7x^3-5x+3)-(2x^2+5x-7)

=>7x^3-5x+3-2x^2-5x+7

=>7x^3-2x^2+(-5x-5x)+(3+7)

=>7x^3-2x^2-10x+10

Working rule:-

If we subtract second polynomial from first polynomial then we have to change the signs of each term in the second polynomial.
