Will give 30 points add or subtract. show your work for each problem a. (x^2-4x+5)+(7x^2+2x-3) b. (7x^2+4x--3x+1)

To solve this problem you must apply the proccedure shown below:

a) You must sum terms with same exponents, therefore, you have that the sum of these two polynomials is:

b) First, you must mulitply the signs of the second polynomial by the negative sign, and them, you apply an algebraic sum. Therefore, the result is:

The answers are: a); b)

black/brown
