Question

-4x^2+ 2x-5(1 + x)
What expression is equivalent to the given expression?

Answer 1

The equivalent expression to the original algebraic expression is
`-4x^2 -3x -5`

What are equivalent expressions?

Equivalent expression are expression that are similar although they may appear different when written down.

We are to find the equivalent expression to the algebra expression:

`-4x+2x-5(1+x)`

To find the equivalent expression, we can expand the given expression by distributing 5 to open the bracket.

`= -4x^2+ 2x-5 -5x`

By rearrangement of common terms;

`= -4x^2 -5x+ 2x -5`

`= -4x^2 -3x -5`

Thus, the equivalent expression to the original algebraic expression is = -4x^2 -3x -5

Answer 2

-4x^2 + 2x - 5 - x

-4x^2 + x - 5

-4x^2 + x - 5 there are no more like terms.
