Answer

-8 + 2r

Step 1: Andika vigezo vilivyotolewa. Tunapewa thamani za $k = -2$ na $p = 2$ . Thamani ya $r$ haijatolewa katika swali.

Step 2: Badilisha thamani za $k$ na $p$ kwenye usemi $k(2p-r)$ . $k(2p-r) = (-2)(2(2)-r)$

Step 3: Rahisisha usemi ndani ya mabano kwanza. $(-2)(4-r)$

Step 4: Panua usemi kwa kuzidisha $-2$ na kila neno ndani ya mabano. $(-2)(4) - (-2)(r)$ $-8 + 2r$ Kwa kuwa thamani ya $r$ haijatolewa, usemi hauwezi kurahisishwa zaidi kuwa namba moja.

Thamani ya usemi ni $\boxed{-8 + 2r}$ . Drop the next question.
