Solve quadratic formulax^2-4x+3=0
bekas [8.4K]

The general formula for a equation of the form:

ax^2+bx+c=0

is:

x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:

\begin{gathered} x=\frac{-(-4)\pm\sqrt[]{(-4)^2-4(1)(3)}}{2(1)} \\ =\frac{4\pm\sqrt[]{16-12}}{2} \\ =\frac{4\pm\sqrt[]{4}}{2} \\ =\frac{4\pm2}{2} \end{gathered}

then:

x_1=\frac{4+2}{2}=\frac{6}{2}=3

and

x_2=\frac{4-2}{2}=\frac{2}{2}=1

Therefore, x=3 or x=1.

The number of mosquitoes in Brooklyn (in
stealth61 [152]

Answer:

Maximum is 4

Step-by-step explanation:

M(x) is quadratic function, so we need to fin maximum.

m(x)=-x(x-4)

m(x)=-x^2+4x

To find a maximum we need to find m’

M’(x)=-2x+4

M’(x)=0 if x=2

The maximum is in the point x=2

M(2)=-2(2-4)=4
