Answer 1

Step-by-step explanation:

given 1 expression =4x3+8x2+7

second expression =2x2+x-1

so they asked that what should subtracted from the 1 one to get second so first what should we do is subtract both the expressions so that we will get one expression which is solution

SO HERE IS THE ANSWER

4x3+8x2+7

0x3+2x2 -1 +0x

so we know that the symbols will change while doing subtraction so we have to change only the second expression which is down

4x3+6x2+8-x is the expression which is the answer
