Question

Find the sum of the given polynomials.

ax + by + c, 2ax - 3by + c, and by - c
3ax - by + c
3a + x - bc
3ax + by - cd
bx - 3bc + a

Answer 1

3ax-by+c

Explanation:

Answer 2

3ax-by+c

Explanation:

Step1: Collect all the like terms

Like terms are similar variables, for example;

• (ax, 2ax) are all like terms since they have a common variable (ax)
• (by, -3by,by) are also like terms since they have a common variable (by)
• (c, c, -c) are also like terms since they have a common variable (c)

Step 2: Sum of all the groups of like terms

(ax+2ax)+(by-3by+by)+(c+c-c)=3ax-by+c

The answer is 3ax-by+c
