What is cube of binomial mean?
The cube of a binomial is the cube of two terms separated by an addition or subtraction sign, such as (2a + 3b) or (ab - cd).For example, (2x - 5y)3 = 8x3 - 40x2y + 50xy2 - 20x2y + 100xy2 - 125y3.The detailed method of expanding this binomial is : (2x - 5y)3 = (2x - 5y)(2x - 5y)(2x - 5y) = (4x2 - 20xy + 25y2)(2x - 5y) = 8x3 - 40x2y + 50xy2 - 20x2y + 100xy2 - 125y3
Multiply 3 plus 2x and 3-2x?
(3+2x)*(3-2x) = 9 - 4x2 [remember that (a+b)*(a-b)=a2 - b2]
What is the answer to 2x plus 3 equals 4x-7?
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x
2x\3+8=14?
2x/3 + 8 = 14 2x/3 = 6 2x = 18 x = 9
What is the answer to 2x equals X plus 3?
2x = x+3 2x-x = 3 x = 3
What is 2x-3 cube?
(2x - 3)3 = (2x - 3)(2x - 3)(2x - 3) = (4x2 - 12x + 9)(2x - 3) = 8x3 - 36x2 + 54x - 27
What is the volume of a cube with sides of 2x?
2x x 2x x 2x = 8x3

What is the volume of a cube if one of its sides is 2x?
It is 8x^3 cubic units.
What is twice the cube of a number?
2n3
4x2 - 0x - 9?
(2x - 3)(2x + 3)(2x-3)(2x+3)
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
What do you do to find the surface area of a shape?
Rectangular Prisim 2x(area of front)+2x(area of side)+x2(area of length) Cube 2x(area of side)+2x(area of side)+2x(area of side)
How do you solve x plus 2x equals 3?
2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3
2x- 1 x 3?
if you mean 2x-1*3 then the answer is: 2x-3
