given that The value of P for which the expression x^3 + x^2 - 5x + P will be divisible by (x-2)...so (x-2) is the Root of x^3 + x^2 - 5x + P..
so
(x-2)(x^3 + x^2 - 5x + P) will be equal to 0
substitute x=2 in the Equation....x^3 + x^2 - 5x + P=0
2^3 + 2^2 - 5(2) + P=0
8+4 -10 +p =0
12-10 +p =0
p = -2..
so
(x-2)(x^3 + x^2 - 5x + P) will be equal to 0
substitute x=2 in the Equation....x^3 + x^2 - 5x + P=0
2^3 + 2^2 - 5(2) + P=0
8+4 -10 +p =0
12-10 +p =0
p = -2..
RohitSaketi:
all types
like x-2 ,x-3 etc
yess...if they give it in the question
Means in any expression type we have to solve to get zero
yes
Ok ,thank u very much bro
try other similar sums in ur book and see
Yup
if u still have doubts ask me here..or post questions..and remind me ..i ll answer
Yaa,ofcourse
