What is 5d² + 4d - 3 less 2d² -3d + 4?

Solution:

We have to find 5d² + 4d - 3 less 2d² - 3d + 4.

= 5d² + 4d - 3 - (2d² - 3d + 4)

By multiplying the negative sign inside the brackets

= 5d² + 4d - 3 - 2d² + 3d - 4

On grouping like terms and adding them up,

= 5d² - 2d² + 4d + 3d - 3 - 4

On further simplification, we get

= 3d² + 7d - 7

Therefore, 5d² + 4d - 3 less 2d² - 3d + 4 is 3d² + 7d - 7.

What is 5d² + 4d - 3 less 2d² - 3d + 4?

Summary:

5d² + 4d - 3 less 2d² - 3d + 4 is 3d² + 7d - 7.
