Svetlanka [38]

Answer: $6+\sqrt{21}\ \text{and}\ 6-\sqrt{21}$

Step-by-step explanation:

Given

Quadratic equation is

$x^2-12x+15=0$

Solving by completing the square method

$\Rightarrow x^2-2\cdot 6\cdot x+15=0\\\text{add and subtract 36}\\\Rightarrow x^2-2\cdot 6\cdot x+15+36-36=0\\\Rightarrow x^2-2\cdot 6\cdot x+36+(-36+15)=0\\\text{using}\ (a-b)^2=a^2+b^2-2ab\\\Rightarrow (x-6)^2-21=0\\\Rightarrow (x-6)^2=21\\\Rightarrow x-6=\pm \sqrt{21}\\\Rightarrow x=6\pm \sqrt{21}$

The solution set of the equation is $6+\sqrt{21}\ \text{and}\ 6-\sqrt{21}$

Please help me <br>solve 3x+1/2=3/8+x

gavmur [86]

Answer:

x= - $\frac{1}{32}$

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+ $\frac{1}{2}$ = $\frac{3}{8}$ Next move 1/2 to the right side. Now your equation is 4x= $\frac{-1}{8}$ . Next divide both sides by 4 to isolate "x." Now your equation is x= - $\frac{1}{32}$

Hope this helped and have a great day.
