Which function has real zeros at x = –8 and x = 5? g(x) = x2 3x – 40 g(x) = x2 3x 40 g(x) = x2 14x – 40 g(x) = x2 14x 40

g(x) = for real zero x= -8, x =5.

Step-by-step explanation:

Given : real zeros x =-8 , x =5 .

To find : Function.

Solution : We have given that:

Factor theorem states that (x-r) is a factor of the polynomial function f(x) if and only if r is a root of the function f(x).

Since, we know that the root of the function i.e f(x) are -8 and 5 then the function has the following factor:

(x+8) = 0 and (x-5) =0

Zero product property states that if ab = 0 if and only if a =0 and b =0.

By zero product property,

(x+8)(x-5) = 0

Now, distribute each terms of the first polynomial to every term of the second polynomial we get;

x (x-5 ) +8(x-5)

.

.

Therefore, g(x) = for real zero x= -8, x =5.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
