The solution to $\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$ is x = 1

<h3>How to solve the equation?</h3>

The equation is given as:

$\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$

Split the equation as follows:

$y\ =\ \left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}$

$y = 1 + x^2$

Next, we plot the graph of both equations (see attachment)

From the attached graph, the intersection point is (1, 2)

Remove the y value

x = 1

Hence, the solution to $\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$ is x = 1

Graph each equation 3x+5y=12

The graph of the equation, 3x + 5y = 12, is the graph attached in the image below.

<h3>How to Graph a Linear Equation?</h3>

The slope (m) and the y-intercept (b) of a linear equation can easily be determined by writing a linear equation in slope-intercept form, y = mx + b.

The slope of the line is the rise/run, while the y-intercept tells us at what point on the y-axis the line intercepts.

Rewrite 3x + 5y = 12, in slope-intercept form:

5y = - 3x + 12

y = -3/5x + 12/5

The slope of the line of the equation is -3/5 while the y-intercept is 12/5.

Therefore, the graph of the equation, 3x + 5y = 12, is the graph attached in the image below.
