Question

4.Find the zeros of the quadratic
polynomial. x2 +7x +10 *
O 5,2
O -2,-5
O 2,-5
O None of these​

Answer 1

Answer:

The zeroes of the polynomial are -2,-5

Step-by-step explanation:

We have been given a quadratic equation in the question. A quadratic equation is a polynomial with highest degree 2.

The zeroes of a polynomial mean the factors of the equation that we get when we equate the polynomial to zero.

Here equating the given equation to zero:

$x^{2} +7x+10=0\\x^{2} +5x+2x+10=0\\x(x+5)+2(x+5)=0\\(x+5)(x+2)=0$

x=-5,-2

The zeroes of the polynomial are -5 and -2.
