Rewrite the equation by completing the square.<br>x^2-2x+1=0

kaheart [24]

Answer:

(x - 1)² = 0

Step-by-step explanation:

Given

x² - 2x + 1 = 0 ( subtract 1 from both sides )

x² - 2x = - 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = - 1 + 1

(x - 1)² = 0

Help me solve this equation 3x-7=4x

Sauron [17]

Hey!

Let's write it, $3x-7=4x$
Add $7$ to both sides,
$3x-7+7=4x+7$
$3x=4x+7$
Subtract $4x$ from both sides.
$3x-4x=4x+7-4x$
$-x=7$
Since we don't want a negative variable, we have to divide both sides by $-1$ .
$\frac{-x}{-1}=\frac{7}{-1}$
Our answer would be,
$x=-7$

Thanks!
