Addition and Subtraction of Polynomials Answers

(3a2 – 5ab + b2) + (–3a2 + 2b2 + 8ab)Which of the following shows the sum of the polynomials rewritten with like terms grouped together?

Use your result from the previous task to find the sum.

Add (1.3t3 + 0.4t2 – 24t) + (8 – 18t + 0.6t2)For each term in the second polynomial, enter the letter showing where that term should be placed to add the polynomials vertically. 1.3t3 + 0.4t2 + (–24t) = 0.6t2

= 0t3

= 8

= –18t
