What exactly does 3x 12x 9 do?

This can be multiplied with crosses.

The quadratic term coefficients can be turned into one and three. Constant terms.

It can be split into minus three and minus three. So the whole can be (3x-3) (x-3) = 0, so his solution can be one or three.

According to the inscription column, it is calculated as follows:

3x²-12x+9

3（x²-4x+3）

3（x-3）（x-1）

3x²－12x＝-9

The equation is divided by 3 left and right at the same time

x²－4x＝－3

x²－4x＋3＝0

Use cross multiplication.

x－3）（x－1）＝0

x＝3x＝1

Divide 3 first, and then calculate according to the algorithm of the one-dimensional quadratic equation to get the answer.

Answer: Solution: x2-4x+6=9, that is, x2-4x=3,6-3x2+12x=6-3(x2-4x)=6-3 3=6-9=-3

So the answer is: -3

This should be a special wind set with s.,And then last time I said it.。

First calculate 16*4=64, then move to the right of the equal sign, 64+17=81, that is, 9x=81, and find x=9

First, let's count 16 4. 16 4 = 64, and then the first two sides of the type at the same time to consume the rent plus 64 is 9x-64 + 64 = 17+ x = 17 + 64 = 81 and then divide the two sides by 9 at the same time to get sleepy, 9x 9 = 81 9, so the final answer to the solution is x=9.

9x 81x 9

Summary. 2x²+3x=11x

2x²+3x=11x

2x²+3x=11x

Solution: 2x +3x a 11x 0

x(2xa8) 0

2xa8 0x2 4

So the equation solution is: x1 0x2 4

There is no solution to this question.

Problem solving process: x +4x-9=2x-11

x +4x-9-2x+11=0

x + (4x-2x) + (11-9) = 0 (merge similar items to get ) x +2x+2 = 0

x²+2x+1+1=0

x+1) +1=0 (perfect sum of squares and formula merge) (x+1) =-1 (shift).

According to the "square of any positive or negative number is a positive number, and the square of 0 is 0", it can be seen that the square of no number is negative, so there is no solution to this problem.

It's elementary math, depending on what method I use.

x²＋3x(x-3)-9

x -9 + 3x (x-3) (9 is considered to be 3 squared) = (x+3) (x-3) + 3x (x-3).

x-3）（4x+3）

Using the cross multiplication method, the coefficient of the quadratic term 2 is decomposed into 2 1, and the constant term -9 is decomposed into 3 (-3).

2x+3）（x-3）
