Find each of the following products : 3×(−1)
As we know that (−)×(+)=−
Therefore, on Multiplying this we get
=−(3×1)=-3
Find each of the following products:
(3y−8)×(5y−1)
(9x2−x+15)×(x2−x−1)
Look at the pattern and fill in the blanks:
4=3×1+1, For 1st term or n=1
7=3×2+1, For 2nd term or n=2
10=3×3+1, For 3rd term or n=3
13=3×4+1, For 4th term or n=4
16=3×5+1, For 5th term or n=5
∴Expression for nth term is 3n+1
(iii) For n=30, 3×____+1=____.
