Question

find the zeroes of f(x) = x3 – 12x2​

Answer 1

$Given \: f(x) = x^{3} - 12x^{2}$

/* To find zeroes , we must take f(x) = 0 */

$x^{3} - 12x^{2} = 0$

$\implies x^{2} (x-12) = 0$

$\implies x^{2} = 0 \:Or \:x-12 = 0$

$\implies x^{2} = 0 \:Or \:x = 12$

Therefore.,

$0, 0 \:and \: 12 \: are \: zeroes \: of \:f(x)$

Answer 2

Answer:

8

Step-by-step explanation:

f(x)=3x-12*2

f(x)=

3x-12*2=0

3x-24=0

3x=24

x=24/3

x=8
