Question

Find the zeros of quadratic polynomial p(x)=(x+5)(x-7)

Answer 1

Answer:

X= 5, , -7 are the zeros of quadratic polynomial p(x)=(x+5)(x-7)

Step-by-step explanation:

(x+5)=0

X=-5

(x-7) =0

x=7

Answer 2

Given,

The polynomial, p(x) = (x+5)(x-7).

To find,

The zeros of the polynomial.

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have the following polynomial:

p(x) = (x+5)(x-7)

We can find its zeros by equating both the brackets with zero.

(x+5) = 0, (x-7) = 0

Moving 5 and 7 from the left-hand side to the right-hand side will result in the change of the sign from plus to minus and minus to plus respectively:

x = -5, x = 7

Hence, -5 and 7 are the zeros of p(x) = (x+5)(x-7).
