Answer:

Step-by-step explanation:

$2x^2+16x-8=0$

Simplify:

$x^2+8x=4$

Rewrite in the form $(x+a)^2=b$ :

$x^2+8x=4$

Add $4^2$ to both sides:

$x^2+8x+4^2=4+4^2$

$x^2+8x+4^2=20$

$\left(x+4\right)^2=20$

$x+4=\sqrt{20}$ or $x+4=-\sqrt{20}$

x = -4± $\sqrt{20}$

x= -4± $2\sqrt{5}$

kicyunya [14]

Answer:

The numbers are 44 and 46

Step-by-step explanation:

Let

x, x+2 ----> the two consecutive positive even integers

we know that

$(x+x+2)^{2} =4,048+x^{2} +(x+2)^{2} \\ \\(2x+2)^{2} =4,048+x^{2} +x^{2}+4x+4\\ \\4x^{2}+8x+4=2x^{2}+4x+4,052\\ \\2x^{2} +4x-4,048=0$

Solve the quadratic equation using a graphing calculator

The solution is x=44

see the attached figure

x+2=44+2=46

therefore

The numbers are 44 and 46
