Find the product of (x − 8)2 and explain how it demonstrates the closure property of multiplication. x2 − 64; is a polynomial
x2 − 16x + 64; is a polynomial
x2 − 64; may or may not be a polynomial
x2 − 16x + 64; may or may not be a polynomial

its electric no smoke

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

c
