Add the given polynomials: - 7 m 4 + 5 m 3 + 2 ; 5 m 4 - 3 m 3 + 2 m 2 + 3 m - 6

Given polynomials are - 7 m 4 + 5 m 3 + 2 ; 5 m 4 - 3 m 3 + 2 m 2 + 3 m - 6 First we need to write in the addition form. Thus, the required addition ⇒ ( - 7 m 4 + 5 m 3 + 2 ) + ( 5 m 4 - 3 m 3 + 2 m 2 + 3 m - 6 ) Now we need to arrange all the like terms and then all the like terms are added. = ( - 7 m 4 + 5 m 4 + 5 m 3 - 3 m 3 + 2 m 2 + 3 m - 6 + 2 ) = ( - 2 m 4 + 2 m 3 + 2 m 2 + 3 m - 6 + 2 ) Thus, the required answer is - 2 m 4 + 2 m 3 + 2 m 2 + 3 m - 6 + 2 .

Subtract the second polynomial from the first. x 2 - 9 x + 3 ; - 19 x + 3 + 7 x 2

To subtract Polynomials, first reverse the sign of each term we are subtracting (in other words turn " + " into " - " and " - " into " + " ), then add as usual. Given statement can be written as ( x 2 - 9 x + 3 ) - ( - 19 x + 3 + 7 x 2 ) ⇒ x 2 - 9 x + 3 + 19 x - 3 - 7 x 2 = - 6 x 2 + 10 x Hence, the required answer is ⇒ - 6 x 2 + 10 x .
