Which binomial is equivalent to (xy + z)(xy − z)?

x²y² - z²

Step-by-step explanation:

Note that

(xy + z)(xy - z) are the factors of a difference of squares

a² - b² = (a + b)(a - b)

here a = xy and b = z, thus

(xy + z)(xy - z) = (xy)² - z² = x²y² - z²

answear:

a

step-by-step explanation: a

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
