Question

Combine the like terms to make a simpler expression: 5k (-2k)-(-1)

Answer 1

Hey there, Lets solve this problem together.

Our first step will be to gather like terms


`5*-2k*k+1`

Simplify 5×−2k×k to −5×2k×k


`-5*2k*k+1`

Simplify 5×2k×k to 10k^2


`-10k^2+1`

Answer 2

Answer: The required simpler expression is
`3k-1.`

Step-by-step explanation: We are given to combine the terms to make a simpler expression from the following expression :

`E=5k+(-2k)-(-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

Since the given expression contain terms with unknown variable k and the constant terms, so we can combine them as follows :

`E\\\\=5k+(-2k)-(-1)\\\\=5k-2k-1\\\\=(5-2)k-1\\\\=3k-1.`

Thus, the required simpler expression is
`3k-1.`
