A' s矛mpleachadh abairt
Gl猫 thric th猫id againn air abairtean ailseabrach a a' s矛mpleachadhNuair a th猫id na teirmean co-choltach a chruinneachadh, canaidh sinn gun deach an abairt a 蝉丑矛尘辫濒别补肠丑补诲丑. le bhith 'a' cruinneachadh theirmean co-choltach'.
Thoir s霉il air an abairt \(2x + 5y + x - 3y\)
Tha ceithir teirmean an seo \(2x,\,5y,\,x\\) agus \(- 3y.\)
Tha d脿 theirm co-cheangailte ri \(x\) agus tha a dh脿 co-cheangailte ri \(y\).
Faodaidh sinn a-nis na teirmean le \(x\) a chur c貌mhla agus na teirmean le \(y\) a chur c貌mhla, agus gheibh sinn \(3x + 2y\).
Eisimpleir
Cruinnich teirmean co-choltach agus s矛mplich an abairt ailseabrach seo:
\(a + 4b + 3a - 3b\)
Freagairt
\(4a + b\) (\(a+3a = 4a\) agus \(4b-3b = 1b\))
Feuch a-nis an s矛mplich thu na h-abairtean a leanas.
Question
\(5a + 4b - a + b\)
\(= 4a + 5b\)
Question
\(4x - y - x + 2x\)
\(= 5x - y\)
Question
\(3m + n - m + 4n - 2m\)
\(= 0m + 5n\)
\(= 5n\)
Tha sinn a-nis a' cur d脿 rud c貌mhla gus abairtean ailseabrach a 蝉丑矛尘辫濒别补肠丑补诲丑. 'S e sin iomadachadh a-mach chamagan agus cruinneachadh theirmean co-choltach.
Question
S矛mplich \(3(x - 2y) + 4x\)
\(= 3x - 6y + 4x\)
\(= 7x - 6y\)
Question
S矛mplich \(3(x + y) + 2(x - y)\)
\(= 3x + 3y + 2x - 2y\)
\(= 5x + y\)
