X ^ 3 + 2x ^ 2-11x-12 factorization
Please write down the detailed answer process

x^3+2x^2-11x-12 =(x³－11x)+（2x²-12）=x（x²-11）+（x²-11+x²-1）=x（x²-11）+（x²-11）+（x²-1）=(x²-11)(x+1)+(x²-1)=(x²-11)(x+1)+(x+1)(x-1)=(x+1)(x...

There is a problem that a polynomial subtracts the square of X + 14x-6. Xiaoqiang mistakenly takes it as an addition calculation, and the result is 2x square + 3. The correct result should be more than one

2X squared + 3-2 (x squared + 14x-6)
=2x²+3-2x²-28x+12
=-28x+15

There is a problem which is a polynomial minus x + 14x-6. Xiaoqiang mistakenly takes it as an addition calculation, and the result is 2x-x + 3. What is the correct result? Please write down the answer, the process and the reason

There is a problem which is a polynomial minus x square + 14x-6. Xiaoqiang mistakenly calculates it as an addition. The result is 2x square-x + 3. What is the correct result? Please write the answer, process and reason. This polynomial is 2x square-x + 3 - (x square + 14x-6) = 2x square-x + 3-x square-14x + 6 = x square-15

There is a problem that a polynomial subtracts x + 14x-6. Xiaoqiang mistakenly takes it as an addition calculation, and the result is 2x squared - x + 3. What is the correct result

This x + 14x-6 should be X & # 178; + 14x-6
Let f (x) be the polynomial
Then f (x) + (X & # 178; + 14x-6) = 2x & # 178; - x + 3
Then f (x) = x & # 178; - 15x + 9
f（x）-（x²+14x-6）=x²-15x+9-（x²+14x-6）=-19x+15

A polynomial a subtracts the quadratic power of X + 14x - 6. Xiao Ming mistakenly takes it as an addition calculation, and thus gets the result of 2x - x + 3

The power of a + X + 14x-6 = the power of 2x-x + 3
A = the second power of x-15x + 9
So a minus (the second power of X + 14x-6) = 15-29x

There is a problem that a polynomial subtracts x2 + 14x-6. Xiaoqiang mistakenly takes it as an additive calculation and gets 2x2-x + 3______ , the correct result______ ．

According to the meaning of the question: (2x2-x + 3) - (x2 + 14x-6) = 2x2-x + 3-x2-14x + 6 = x2-15x + 9, the correct result is: (2x2-x + 3) - 2 (x2 + 14x-6) = 2x2-x + 3-2x2-28x + 12 = - 29x + 15, so the answer is: x2-15x + 9; - 29x + 15

2 of 0.01 (2x-3) = 0.02-2x of 0.02
We use the de denominator solution,

The equation 0.01 Part 2 (2x-3) = 0.02 part (0.02-2x) can be obtained by multiplying both sides by 0.02
4(2x-3)=0.02-2x
8x-12=0.02-2x
10x=12.02
The solution is x = 1.202

0.02 (2x-3) - 2.5 of 0.01 = 0.01 (0.02-2x) - 3.5 of 0.02

0.02 (2x-3) - 2.5 of 0.01 = 0.01 (0.02-2x) - 3.5 of 0.02
2（2X-3）-2.5=0.5(0.02-2X)-3.5
4X-6-2.5=0.01-X-3.5
4X+X=6+2.5+0.01-3.5
5X=5.01
X=5.01÷5
X=1.002

2 of 0.01 (2x-3) - 2.5 = 0.02-2x-7.5 of 0.02

2 of 0.01 (2x-3) - 2.5 = 0.02-2x-7.5 of 0.02
200（2X-3)-2.5=50(0.02-2X)-7.5
400X-600-2.5=1-100X-7.5
400X+100X=600+1+2.5-7.5
500X=596
X=596÷500
X=1.192
