Answer 2

QUESTION:

K^2-k+1,-5k^2+2k-2 and 3k^2-4k+1 find the sum

ANSWER:

In order to find the sum we use the brackets.

$( {k}^{2} - k + 1) + ( - 5{ k}^{2} + 2k - 2) + ( 3{k}^{2} - 4k + 1)$

we add the like terms.

In algebra, terms which have the same variable and power are called like terms.

Opening the bracket.

${k}^{2} - k + 1 - 5 {k}^{2} + 2k - 2 + 3 {k}^{2} - 4k + 1 \\ = - {k}^{2} - 3k$

FINAL ANSWER :

$\huge\blue{ {-k}^{2} - 3k}$
