Factorization 4x-4x ^ 2 y + 2xy-2
(2-2xy)(2x-1)
Use the complete square formula to factorize the following problems 4xy ^ 2-4x ^ 2 Y-Y ^ 3 3-6x + 3x ^ 2
4xy^2-4x^2 y-y^3
=-y(4x²-4xy+y²)
=-y(2x-y)²
3-6x+3x^2
=3(x²-2x+1)
=3(x-1)²

Given TaNx = 2, what is the value of tan2 (x - π / 4)?
tan2x=2tanx/(1-tan²x)=-4/3
The original formula = Tan (2x - π / 2) = - cot2x
=-1/tan2x
=3/4
How to calculate 15 * 15 * 15-15 * 15
15*15*15-15*15
=15*15*（15-1）
=15*15*14
=15*15*2*7
=15*30*7
=450*7
=3150
It is known that m (4,2) is the midpoint of line AB cut by ellipse x2 + 4y2 = 36, then the equation of line L is______ ．
Let K be the slope, then the equation of the line L is Y-2 = K (x-4), that is kx-y + 2-4k = 0, and the equation of the ellipse is reduced to & nbsp; (1 + 4k2) x2 + (16k-32k2) x + 64k2-64k-20 = 0, and the solution is k = - 12, so the equation of the line L is & nbsp; X + 2y-8 = 0, so the answer is x + 2y-8 = 0
16.9 + 6.3x = 18.79 how to solve the equation detailed method
16.9+6.3x=18.79
6.3x=18.79-16.9
6.3x=1.89
x=1.89÷6.3
x=0.3

Given that the image of the function FX = KX ^ 2-3x + 1 has a common point with the X axis on the right side of the origin, the value range of the real number k is?
Given that the image of the function FX = KX ^ 2-3x + 1 has a common point with the X axis on the right side of the origin, the value range of the real number k is?
When k = 0, f (x) = - 3x + 1 = 0, x = 1 / 3, which is in line with the meaning of the question;
If K is not 0, f (x) is a quadratic function and has a common point, then the discriminant = 9-4k > = 0, then K0 is obtained, that is, both are positive, so it is consistent with
The value of K is K
How to use 50 * 28 * 4 for simple calculation
Change the original formula to 50 * 4 * (20 + 8) and then open the brackets. The multiplication is 200 * 20 + 200 * 8 = 4000 + 1600 = 5600
