Alex claims that the product of x^2 and x^4+x^2-1 will be x^8+x^4-x^2. explain the error made by alex

Step-by-step explanation:

the product is a result of multiplicationso lets multiply

x^2 (x^4 + x^2 - 1) =

x^6 + x^4 - x^2

ok...his mistakes are occurring because he is multiplying the exponents when he is supposed to be adding them.

exponent rule : x^a * x^b = x^(a + b)

answer: i'm not sure

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
