9y cubed plus 2y squared
When you see "y times 2," it means you are multiplying the variable y by the number 2. So the expression "y times 2" can be written as 2y. This is a simple algebraic expression where the coefficient of y is 2.
To find 2 times the sum of y and 5, you first need to calculate the sum of y and 5 by adding y and 5 together. Once you have the sum, you then multiply it by 2 to find the final result. The expression for this calculation would be 2(y + 5).
xcubed-1 Answer::(X-1)(Xsquared+X+1) when you factor xcubed minus a number its the same thing as x cubed minus y cubed and x cubed minus y cubed factors to:: (x-y)(xsquared+xy+y squared) the first factor, (x-y), is the cubed root of the first and the cubed root of the second, so in the answer i have (x-1), which is x cubed minus one cubed :) the second factor, (xsquared+xy+ysquared), you take the first number squared, Xsquared, then the first and second one multiplied together, XY, and then the second number squared, Ysquared, so in the answer i have (xsquared+x+1), which is x squared, then x times 1 which is just x, and positive 1, which is negative 1 squared :) x^3 - 1
Centimetres squared is a measure of area. Metres cubed is a measure of volume. If one has X centimetres squared as the area of the base of an object, and the object has a height of Y centimetres then the volume of the object is XY centimetres cubed. 1 metre contains 100 centimetres. 1 metre squared contains 100 x 100 = 10,000 centimetres squared 1 metre cubed contains 100 x 100 x 100 = 1,000,000 centimetres cubed
9y cubed plus 2y squared
2x^2y^3(4x^2 - 3xy + 1)
y^(3) - 2y^(2) + 4y Factor out 'y' Hence y(y^2 - 2y + 4) This will not factor any further.
Y squared (Y^2)
You have to put your heart into it!

x cubed y cubed z squared
x to the 5th power times y to the fourth power
(75y - 12x^2) * y = 75y^2 -12x^2y 75y - (12x^2 * y) = 75y -12x^2y
(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
(x2y2)3 + (x3y3)2 = 2x6y6.
multiply by 2y/x
