Question

which of the following is a zero of the poly nomial p(x)=(x+5)(x-2)​

Answer 1

Answer:

Explanation:

We have been given the polynomial p(x)=2x+5.

Zero of the polynomial is the x-intercept. Hence, in order to find the zero of the polynomial, we set p(x)=0

Therefore, we have

Subtract 5 to both sides

Divide both sides by 2

Therefore, the zero of the polynomial p(x)=2x+5 is

Answer 2

Answer:

p(x)=x(x-2)+5(x-2)

=x²-2x+5x-10

=x²+3x-10
