Find the sum of 4x3 + 2x2 - 4x + 3 and 7x3 - 4x2 + 7x + 8.
Solution:
The two given equations are
4x3 + 2x2 - 4x + 3 and 7x3 - 4x2 + 7x + 8
We have to find the sum of both
= 4x3 + 2x2 - 4x + 3 + 7x3 - 4x2 + 7x + 8
By rearranging the terms
= 4x3 + 7x3 + 2x2 - 4x2 - 4x + 7x + 3 + 8
So we get
= 11x3 - 2x2 + 3x + 11
Therefore, the sum is 11x3 - 2x2 + 3x + 11.
Find the sum of 4x3 + 2x2 - 4x + 3 and 7x3 - 4x2 + 7x + 8.
Summary:
The sum of 4x3 + 2x2 - 4x + 3 and 7x3 - 4x2 + 7x + 8 is 11x3 - 2x2 + 3x + 11.
