How would you factor
Svetach [21]
\bf 4x^3+2x^2+2x\implies 2x(2x^2+x+1)

so in short, the only factoring doable to it, without any complex factors, is that of taking the common factor of 2x.

now, the trinomial of 2x²+x+1, will not give us any "real roots", just complex or "imaginary" ones.

if you have already covered the quadratic formula, you could test with that, or you can also check that trinomial's discriminant, and notice that it will give you a negative value.

\bf \begin{array}{llcccll}
& 2 x^2& +1 x& +1\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad \qquad 1^2-4(2)(1)
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}

A ball is thrown into the air with an initial upwards velocity of 60ft/s. Its height (h) in feet after t secons is given by the
Strike441 [17]
I believe you will sub. in 3 for t so h=-16(3)^2 + 60(3)+6. then you will just solve!
h=-16(9)+60(3)+6
h= -144 + 180 + 6
h= 42
 so the answer to your question is c. 42 Feet
 Hope this helps! :)
