Question

if x-2 is a factor of x3-3x2 + kx then find k ​

Answer 1

Answer:

__________

x - 2

x = 2

$\mathfrak\red{Solution}$

x^3 - 3x^2 + Kx

2^3 - 3 × 2^2 + k × 2

8 - 3 × 4 + 2k

8 - 12 + 2k

-4 + 2k

2k = 4

k = $\frac{4}{2}$

k = 2 ✓

Answer 2

Answer:

x-2)x³-3x²+kx(x²-x

x³-2x².

-x² +kx

-x²+2x.

0.

=>kx-2x = 0

=>k-2=0

=>k=2
