Lösung 2.2:2c
Aus Online Mathematik Brückenkurs 1
We can simplify the left-hand side in the equation by expanding the squares using the squaring rule
Thus, the equation is
Now, move all x's to the left-hand side (subtract 6x from both sides) and the constants to the right-hand side (add 16 to both sides)
Divide both sides by 10 to get the answer
Finally, we check that \displaystyle x=2 satisfies the equation in the exercise
