Question

X-2√2-6=0 slove it and make it quadratic equations

Answer 1

Answer:

$\Large\boxed{x=2\sqrt{2}+6=8.8}$

Step-by-step explanation:

Given:

$\Large\boxed{\textnormal{LESSON: QUADRATIC EQUATIONS}}$

X-2√2-6=0 (by using with quadratic equations)

To solve this problem, first you have to use the quadratic equations from left to right numbers. Isolate by the x on one side of the equation.

Solutions:

Quadratic equations formula.

$\Large\boxed{\textnormal{QUADRATIC EQUATIONS FORMULA}}$

$\displaystyle \frac{-b\pm\sqrt{b^2-4ac} }{2a}$

First, you subtract by -2√2-6 from both sides.

$\displaystyle x-2\sqrt{2}-6-(-2\sqrt{2}-6)=0-(-2\sqrt{2}-6)$

Solve.

$\displaystyle x=-(-2\sqrt{2}-6)$

Substitute with parenthesis.

$\displaystyle -2\sqrt{2}-6$

$\displaystyle -(-2\sqrt{2})-(-6)$

Change negative sign to positive sign.

$\displaystyle -(-a)=a$

$\displaystyle \boxed{2\sqrt{2}+6}$

$\Large\boxed{x=2\sqrt{2}+6}$

As a result, the correct answer is x=2√2+6.
