x(x - 6)(x + 2)
x = 0
x = 6
x = -2
The zeros are 0, 6, and -2

Please help me I need to solve by factoring!! ​
Sveta_85 [38]

Answer:

x=5

Step-by-step explanation:

3x^2=15x

Subtract 15x from both sides

3x^2-15x=0

Factor out 3x

3x(x-5)=0

Since 0 divided by any number is zero, we get that:

x-5=0

x=5

Wen is factoring the polynomial, which has four terms. 6x3 – 12x2 7x – 14 6x2 (x – 2) 7(x – 2) Which is the completely factored
-Dominant- [34]

The completely factored form of the Wen's polynomial, which has the four terms initial, is,

(6x^2+7)(x-2)

<h3>What is the factor of polynomial?</h3>

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

Wen is factoring the polynomial, which has four terms.

6x^3 - 12x^2+ 7x - 14 '

Take out the greatest common factor from the equation and make separate groups as,

6x^2(x - 2)+ 7(x - 2)\\(x-2)(6x^2+7)

Rearrange the above equation as,

(6x^2+7)(x-2)

Thus, the completely factored form of the Wen's polynomial, which has the four terms initial, is,

(6x^2+7)(x-2)

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
vivado [14]

Answer:

15.6km

Step-by-step explanation:

Given the map scale 1:200000

1cm on the map represents 200000 cm on ground or in actual distance

Hence, if distance from Belfast to Larne is 7.8vm on map ;

Actual distance will be :

7.8 * 200000 = 1560000 cm

Converting to km :

Recall :

1000 m = 1km

100 cm = 1 m

Hence,

100000 cm = 1km

Therefore, (1560000 / 100000) km

= 15.6km

Hence, distance between Belfast and Larne is 15.6km
