Question

If two zeroes of the polynomial x2 - 4x -3x+12 are 13 and -V3, then
find its third zero.
App​

Answer 1

Given,

Zeroes of the cubic polynomial p(x) are √13 and -√13

p(x) = x³ - 4x² - 3x + 12

To Find,

The third zero

Solution,

We know,

Sum of zeroes = -(coefficient of x²) / (coefficient of x³)

==> √13 + -(√13) + x = -(-4)/1

==> x = 4

Hence, The third zero is 4

Answer 2

Answer:

Step-by-step explanation:

Its a quadratic equation

So there is no chance of getting a third zero.

It has only two zeroes there are 13 and-$\sqrt{3.$
