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.
