Soal yg sy kepikiran dari temen sy ._
(2x2+x-6) + (x ² - 2x + 4) =
Cara -_-
(2x2+x-6) + (x ² - 2x + 4) =
Cara -_-
(2 × 2 + x - 6) + (x² - 2x + 4)
= (4 + 1x - 6) + (1x² - 2x + 4)
= 1x² + (1x - 2x) + (4 - 6 + 4)
= 1x² - 1x + (-2 + 4)
= 1x² - 1x + 2
(2 × 2 + x - 6) + (x² - 2x + 4)
= (x - 2) + (x² - 2x + 4)
= x² - 2x + x + 4 - 2
= x² - x + 2
Atau
(2x² + x - 6) + (x² - 2x + 4)
= 2x² + x² - 2x + x + 4 - 6
= 3x² - x - 2
Maaf kalo salah jawabannya
