What is the sum of 4x² + 2x - 5 and 722 -- 5x + 2?
1122 - 32 - 3
1122 - 32 + 3
1122 + 30 - 3
1102 + 3x +3
I would be guessing

Sum of 4x² + 2x – 5 and 7x² – 5x + 2 is 11x² – 3x – 3.

Solution:

Given expression:

4x² + 2x – 5 and 7x² – 5x + 2

To find the sum of these expressions.

Sum of 4x² + 2x – 5 and 7x² – 5x + 2

                    = (4x² + 2x – 5) + (7x² – 5x + 2)

                    = 4x² + 2x – 5 + 7x² – 5x + 2

Arrange the terms with same power together.

                    = 4x² + 7x² + 2x – 5x – 5 + 2

                    = 11x² – 3x – 3

Sum of 4x² + 2x – 5 and 7x² – 5x + 2 is 11x² – 3x – 3.
