120:100 or 6:5 so 24:x
if ratios are the same then the reciprocal of one of the ratios times the other ratio should equal 1 so 6/5 times x/24=1
6x/120, x=20
X^2+ 6x - 9 = 0
Use the quadratic formula
x = (<span><span>−b± sqrt (<span>b^2−4ac</span></span>)) / 2a
</span>
a = 1
b = 6
c = -9
x = −6± sqrt (6^2−4(1)(-9) / 2(1)
x = (−6± sqrt(72))/2
so these are your two solutions to the equation
x = 1.243
x = -7.243
=24x^3+225x^2−110x−25

They repeat by adding that same number again and again
