Question

If (x-2) is a factor of x cube - mx sq + 10x - 20 then find the value of m

Answer 1

Answer:

If x minus 2 is a factor of x cube minus M X square + 10 x - 20 then find the value of m Get the answers you need, now!

Answer 2

Since (x - 2) is a factor of f (x),

f (2) = 0

or, 2³ - m (2²) + 10 (2) - 20 = 0

or, 8 - m (4) + 20 - 20 = 0

or, 8 - 4m = 0

4m = 8

m = 8/4

m = 2

Therefore, the required value of m be $\bold{2}$
