usin the factor theorem, show that :

(x-2) is a factor of x³ - 2x² - 9x+18

hence, factorise the expression

x³ -2x² -9x+18 completely

Question

usin the factor theorem, show that :

(x-2) is a factor of x3 - 2x2 -
9x+18

hence, factorise the expression
x3 -2x2 -9x+18 completely

Priyanka Kedia · Accepted Answer

Since (x-2) is a factor of x3 - 2x2 - 9x+18

Thus, (x-2) is a factor of x3 - 2x2 - 9x+18 Now,

usin the factor theorem, show that : (x-2) is a factor of x3 - 2x2 - 9x+18 hence, factorise the expression x3 -2x2 -9x+18 completely
