Question

ADD
(5x² + 7y - 6z²), (4y + 3x², 9x² + 2z² - 9y) and (2y - 2x²)

Answer 1

Given: Four terms (5x² + 7y - 6z²), (4y + 3x²), (9x² + 2z² - 9y) and (2y - 2x²)

To find: The sum of three terms.

Solution:

• So we have provided with three terms.

• Sum of them is:

              (5x² + 7y - 6z²) + (4y + 3x²) + (9x² + 2z² - 9y) + (2y - 2x²)

• Taking same terms together, we get:

              (5x² + 3x² + 9x² - 2x²) + (7y + 4y - 9y + 2y) + (- 6z² + 2z²)

• Now adding up all, we get:

               15x² + 4y - 4z²

Answer:

          So the sum of four given terms are 15x² + 4y - 4z².
