So- A-B-x2212-C-10W3-20W2-x2212-55W-60-x2212-25W2-15W-x2212-10-x2212-5W2-x2212-10W-20-Note- Polynomials with same order will be operated with each other-So- A-B-x2212-C-10W3-20W2-x2212-25W2-x2212-5W2-x2212-55W-15W-10W-60-x2212-10-x2212-20-So- A-B-x2212-C-10W3-x2212-10W2-x2212-30W-30

If A = 10w3+20w2−55w+60,B = −25w2+15w−10 andC = 5w2−10w+20,then A + B - C is equal to ______.10w3+10w2+30w+3010w3+10w2−30w+3010w3−10w2−30w+30None of these

So, A+B−C=(10W3+20W2−55W+60)+(−25W2+15W−10)−(5W2−10W+20)Note- Polynomials with same order will be operated with each other.So, A+B−C=10W3+(20W2−25W2−5W2)+(−55W+15W+10W)+(60−10−20)So, A+B−C=10W3−10W2−30W+30

If A = $10 w^{3} + 20 w^{2} - 55 w + 60$ ,
B = $- 25 w^{2} + 15 w - 10$ and
C = $5 w^{2} - 10 w + 20$ ,
then A + B - C is equal to ______.
$10 w^{3} + 10 w^{2} + 30 w + 30$
$10 w^{3} + 10 w^{2} - 30 w + 30$
$10 w^{3} - 10 w^{2} - 30 w + 30$
None of these
