What are the roots of x^2-4x+4?

Mathematics

The roots are just the zero value of the formula. To find these, we factor:

(x - 2)(x - 2)

(x - 2)^2

to make this into a zero, we set x-2 = 0, then solve for x

x = 2

If x = 2, then the brackets = 0, and those are the roots

The roots are x = 2

The root of the equation x^2-4x+4 is x=2.

To find the root you have to replace y with 0 and then solve for x.

Hope I could help! :)

A shoe store buys a pair of boots from a supplier for $45. The store's manager decides on a markup of 35%. What is the new price
Gnom [1K]

Answer:

The new price of the books = $60.75

Step-by-step explanation:

  • As the original price is: $45

As the markup is: 35% = 35/100 = 0.35

The Markup on the original price is:

0.35 × 45 = $15.75

Hence, the new price of the boots:

$45 + $15.75 = $60.75

Therefore, the new price of the books = $60.75

Solve forx: x^2 = 5x
Akimi4 [234]

Answer:

x = 5

x = 0

Pulling out like terms :

2.1     Pull out like factors :

  x2 - 5x  =   x • (x - 5)

Equation at the end of step  2  :

 x • (x - 5)  = 0

Step  3  :

Theory - Roots of a product :

3.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.
