Question

what are the zeros of the polynomial f(x)=2x square-4x​

Answer 1

Answer:

0 and 2

Step-by-step explanation:

$f(x) = 2 {x}^{2} - 4x$

Whenever f(x) = 0

Then we get the zeroes of polynomial

Solving the equation

$f(x) = 2 {x}^{2} - 4x \\ f(x) = 2x(x - 2)$

Considering

2x = 0 and x-2=0

x =0 and x =2

So 0 and 2 are zeroes of polynomial because substituting x 0,2 in f(x) will give 0.

You can also use Rational Zero theorem to find the zeroes
