Equation using the quadratic fromula for 0.05x^2 + 1.1x = 250

x=60.56, x=-82.56

Step-by-step explanation:

Solve using quadratic formula

Formula is

0.05x^2 + 1.1x = 250

Subtract 250 on both sides

0.05x^2 + 1.1x - 250=0

a= 0.05, b=1.1 , c=-250

Plug in the values in the formula

Now make two equations , one with +  and one with -

then we solve for x

x=60.56

x=-82.56

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
