Question

find the number of zeros of x square + 4 x + 2

Answer 1

Hii there!!!!

The maximum number of zeroes of the given polynomial is 2. It is so predicted by the highest degree of the polynomial.

Hope it helps. ...

Answer 2

Answer:

The zeroes are -2 + √2 and -2 - √2

Step-by-step explanation:

Given Expression:

$x^2+4x+2$

We have to find zeroes of the given expression.

For this we put given expression equal to 0

So,

$x^2+4x+2=0$

Now to find zero we solve the quadratic equation using quadratic formula,

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-4\pm\sqrt{4^2-4\times1\times2}}{2\times1}$

$x=\frac{-4\pm\sqrt{16-8}}{2}$

$x=\frac{-4\pm2\sqrt{2}}{2}$

$x=-2\pm\sqrt{2}$

Therefore, The zeroes are -2 + √2 and -2 - √2
