\bf 8x^3-10x^2+3x=0\implies x(8x^2-10x+3)=0
\\\\\\
x(2x-1)(4x-3)=0\implies 
\begin{cases}
x=0\implies &x=0\\\\
2x-1=0\implies 2x=1\implies &x=\frac{1}{2}\\\\
4x-3=0\implies 4x=3\implies &x=\frac{3}{4}
\end{cases}

An older person is 4 years older than 7 times the age of a younger person. The sum of their ages is 44. Find their ages
Fynjy0 [20]

Answer:

5 yr and 39 yr

Step-by-step explanation:

Let x = the age of the younger

then 7x + 4 = the age of the older

Now x + 7x + 4 = 44

8x + 4 = 44

8x = 40

x = 5

7x + 4 = 7(5) + 4 =  35 + 4 = 39

Check:  5 + 39 = 44
