We have that
F(x)=x²<span>-10x+44
</span><span>Group
terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete
the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
see the attached figure
The number is 6 bc have of 12 is six
2x^2 + 2x - 242 x^2+2x-24= - 240x^2+4x-24
the equation -240x^2+4x-24=0 has not real solutions because Δ<0
⇒ it could not be factored
