Square of 3x-2-5x equation after formulation
The square of 3x-2-5x
＝（3x+1）（x-2）
If x power of 10 = m and Y power of 10 = n, then 2x + 3Y power of 10 is equal to
Answer: the second power of M is multiplied by the third power of n
The x power of 10 is represented by 10 * and the Y power of 10 is represented by 10 ˇ
2X + 3Y power of 10 = 2x power of 10 multiplied by 3Y power of 10 = 10 * 10 * 10 ˇ 10 ˇ = m × m × n × n = 2 power of M multiplied by 3 power of n

The product obtained by multiplying the square of X + ax + B by X + 2 is the third power of X + 2x + 12. Find the value of a, B
(x²+ax+b)×(x+2)
=x³+2x²+ax²+2ax+bx+2b
=x³+(2+a)x²+(2a+b)x+2b
=x³+2x+12
∴2+a=0,2a+b=2,2b=12
∴a=-2,b=6.
It is known that the product of x square + ax + B multiplied by X + 3 is X Cubic + 2x + 33, and the values of a and B are obtained
a+b=2
3a+b=33
Subtraction of two formulas
2a=33-2
2a=31
a=15.5
b=2-a=2-15.5=-13.5
