Question

Select the correct difference.

5d 2 + 4d - 3 less 3d 2 - 2d + 4

2d2 + 2d + 1

2d2 + 6d - 7

2d2 + 6d + 7

-2d2 - 6d + 1

Answer 1

(5d^2 + 4d - 3) - (3d^2 - 2d + 4) distribute the - to the second expression
5d^2 + 4d - 3 - 3d^2 + 2d - 4 combine like terms
2d^2 + 6d -7 final answer
B is the answer

Answer 2

Option B is correct

`2d^2+6d-7`

Explanation:

Difference states that subtracting one number from another.

We have to find the correct difference.

`5d^2 + 4d-3` less
`3d^2-2d+4`

then;

`(5d^2+4d-3)-(3d^2-2d+4)`

Using distributive property i.e
`a \cdot (b+c) = a\cdot b+ a\cdot c`

`5d^2+4d-3-3d^2+2d-4`

Combine like terms;

`2d^2+6d-7`

Therefore, the correct difference is,
`2d^2+6d-7`
