What substitution should be used to rewrite 16(x3 + 1)2 – 22(x3 + 1) – 3 = 0 as a quadratic equation? u = (x3) u = (x3 + 1) u = (x3 + 1)2 u = (x3 + 1)3

answer:

step-by-step explanation:

we have been given the equation

we have to rewrite this equation as a quadratic equation.

looking into the given equation, we can see that we have exponent 2 on the expression (x^3+1).

since the quadratic equation is in the form

hence, we can assume

so, the equation will become

hence, the required substitution is given   by

step-by-step explanation:

c

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.
