Which shows 542 − 462 being evaluated using the difference of squares method?
542 − 462 = (2916 + 2116)(2916 − 2116) = 4,025,600
542 − 462 = (54 + 46)(54 − 46) = (100)(8) = 800
542 − 462 = 2916 − 2116 = 800
542 − 462 = (54 − 46)2 = 82 = 64

Step-by-step explanation:

The method finding difference of squares is given by :-

Replace a=54 and b=46, then we get the evaluation of by using the difference of squares method as :

Hence, the second option is the correct option.

(- 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 )

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
