Solve (x-3)^2 =5 completing the square

otez555 [7]

Answer:

x = 3 ± √5

Step-by-step explanation:

The expression (x - 3)² = 5 doesn't need completing the square to solve (this is the step after you finish completing the square):

Step 1: Square root both sides

x - 3 = ±√5

Step 2: Add 3 to both sides

x = 3 ± √5 = 0.76392, 5.23607

Set up the equation to solve for x

My name is Ann [436]

The three inside angles of a triangle need to equal 180 degrees.

Add the 3 equations together and set to equal 180:

7x+4 + 5x+3 + 2x+5 = 180

Simplify by combining the like terms:

14x + 12 = 180

Subtract 12 from each side:

14x = 168

Divide both sides by 14:

x = 168/14

x = 12

A rectangle with an area of 3990 cm2 is x centimeters wide and (x+4) centimeters long. To the nearest tenth of a centimeter, the

Karolina [17]

Answer: width:60.2 cm

Length: 64.2 cm

Step-by-step explanation:

Given

The area of the rectangle is $3990\ cm^2$

Width of the rectangle is $x\ cm$

Length of the rectangle is $x+4\ cm$

Area of the rectangle is the product of length and width

$\therefore 3990=(x+4)x\\\Rightarrow 3990=x^2+4x\\\Rightarrow x^2+4x-3990=0\\\Rightarrow x=60.198\ or\ -65.198\ cm\\\text{Neglecting negative term}\\\Rightarrow x=60.198\approx 60.2\ cm$

Width of the rectangle is $60.2\ cm$

Length of the rectangle is $60.2+4=64.2\ cm$
