Problem:
The budget for the groceries is represented by the polynomial 10m²+6m-3. If mother spent 6m²-7m+15 in the supermarket, how much was left? Write your answer in polynomial form.
Answer:
Explanation:
We have the given polynomials 10m²+6m-3 and 6m²-7m+15.
First rule in subtracting polynomials is copying the minuend. So we will copy 10m²+6m-3.
10m²+6m-3 - 6m²-7m+15 = ?
Second, change the sign of each term in the subtrahend.
10m²+6m-3 10m²+6m-3
- 6m²-7m+15 = - 6m²+7m-15
And lastly group or aline like terms then proceed to addition.
10m²+6m-3
- 6m²+7m-15
4m²+13m-18
So the final answer is 4m²+13m-18.
