Answer:

3x (x-3)

Step-by-step explanation

3x^2 - 9x + 0

The equation.

3x^2 - 3^2 × x

What I did here is that I factored out 9x to 3^2 times x.

3x (3x^2 all over 3x - 3^2 × x/ all over 3x)

So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.

3x (x^2-1 - (3^2-1) )

You simplify to get the final answer.

3x (x-3)

Final Answer.

Answer:

y= -8/11 x=-63/11

Step-by-step explanation:

Rewrite equation

Step: Solve6x+y=−10for y

Step: Substitute−6x−10 for y in 4x−3y=14

Step: Substitute −8 /11 for x in y=−6x−10

y= −62 /11 --- (Simplify both sides of the equation)
