Transcript

Ex 14.1, 2 (Method 1) Factorise the following expressions. (x) a๐‘ฅ^2y + bx๐‘ฆ^2 + cxyz a๐‘ฅ^2y = a ร— ๐‘ฅ^2 ร— y = a ร— ๐‘ฅ ร— ๐‘ฅ ร— y b๐‘ฅ๐‘ฆ^2 = b ร— ๐‘ฅ ร— ๐‘ฆ^2 = b ร— ๐‘ฅ ร— y ร— y c๐‘ฅ๐‘ฆ๐‘ง = c ร— ๐‘ฅ ร— y ร— z So, x and y are the common factors. a๐‘ฅ^2y + bใ€–๐‘ฅ๐‘ฆใ€—^2 + c๐‘ฅ๐‘ฆ๐‘ง = (a ร— ๐‘ฅ ร— ๐‘ฅ ร— y) + (b ร— ๐‘ฅ ร— y ร— y) + (c ร— ๐‘ฅ ร— y ร— z) = x ร— y ((a ร— ๐‘ฅ ) + (b ร— ๐‘ฅ ) + (c ร— z) = xy (a๐’™ + by + cz)
