Ahora resolveremos el proceso inverso; es decir conoceremos el producto y llegaremos a la operación indicada. Primero reconoceremos cuando se trata de una diferencia de cuadradosx2 – 25x2 – 25 = ( x + 5 ) ( x – 5)x2 – 16 = ( x + 4 ) ( x – 4)x2 – 100 = (x + 10) (x – 10)x2 – 81 = ( x + 9 ) ( x – 9)4x2 – 64 = ( 2x - 8 ) ( 2x + 8)16x2 – 1 = ( 4x + 1 ) ( 4x – 1)

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:

no he doesnt because "-16' is negatiive
