Question

What is x (3x-6) what is the answer​

Answer 1

Here is your answer

The angles x and (3x-6) are complementary [i.e. sum of angles is 90 degrees]

So,

x + (3x-6)= 90


`=>x + 3x-6= 90`


`=> 4x= 90-6= 84`


`=> x= (84)/(4)`


`=> x= 21`

Now,

x (3x-6)

= 21 (3×21-6)

= 21 (63-6)

= 21× 57

= 1197

Answer 2

x(3x-6)=0

Explanation:

x(3x-6)=0

Two solutions were found :

x = 2

x = 0

Step by step solution :

Step 1 :

Step 2 :

Pulling out like terms :

2.1 Pull out like factors :

3x - 6 = 3 • (x - 2)

Equation at the end of step 2 :

3x • (x - 2) = 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.

Solving a Single Variable Equation :

3.2 Solve : 3x = 0

Divide both sides of the equation by 3:

x = 0

Solving a Single Variable Equation :

3.3 Solve : x-2 = 0

Add 2 to both sides of the equation :

x = 2

Two solutions were found :

x = 2

x = 0
