Quadratic equation whose roots are 6 and -5

Quadratic equation is x² - x - 30

Step-by-step explanation:

⇒ Factors are (x - 6) and (x + 5)

⇒ (x - 6)(x + 5) = x² + 5x - 6x - 30 = x² - x - 30

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:

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
