(CD - ab)^2 = (CD - ab)(CD - ab)
= c^2 d^2 - 2abcd + a^2b^2
Try it with say a = 4, b = 3, c = 2 & d = 1:
Then CD = 2 and ab = 12 so CD - ab = -10 and squared = 100
c^2 = 4
d^2 = 1 so c^2d^2 = 4 x 1 = 4
a^2 = 16
b^2 = 9 so a^2b^2 = 16 x 9 =144
2abcd = 48
giving 4 - 48 + 144 = 100. Shazam!

What is 7x 7y as the distributive property?
To expand the expression 7x(7y) using the distributive property, you distribute the 7x to both terms inside the parentheses. This results in 7x * 7y = 49xy. The distributive property allows you to multiply each term inside the parentheses by the term outside the parentheses, simplifying the expression.
(9xcubed-3) - (4xsquared plus 4) plus (5xcubed plus 5xsquared)?
You can expand the first expression in parentheses, then add or subtract like terms.
How do you expand a linear equation?
Not quite sure what you want to expand. One thing you can do is multiply both sides of the equation by the same (non-zero) number.
What the distributive property to expand the following expression. -2(2.1x plus 3y - 1.8)?
-4.2x - 6y + 3.6
For what numbers is the following equation true a plus b squared is equal to a squared plus b squared?
(a + b)² = a² + b². If you expand the left side, you have a² + 2ab + b² = a² + b². Subtracting a² and b² from both sides, you have: 2ab = 0. So if either a=0 or b=0 the equation is satisfied.

How do you expand a minus b squared?
It depends if there are parentheses or not... for example if the problem looks like this: (-b)^2, then do (-b)x(-b) and get b^2 OR if the problem looks like this: -b^2, then do -(b)(b) which would be -b^2 As u can see, the parentheses' placement make a large difference in the final answer.
How do you expand brackets with algebra?
Same as parentheses. Brackets are used simply as a different type of parentheses, to make it easier to match the left and the right side.
Is a squared plus b squared the same as a plus b squared?
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
Expand 3(x plus 4)?
You simply multiply the expression on the outside (in this case, 3) by each of the expressions inside the parentheses, and add everything up. In this case, 3x + 3 times 4.

how do we expand brackets if its triple brackets?
To expand three brackets, expand and simplify two of the brackets then multiply the resulting expression by the third bracket. (FAIZAN BHAI GHAZI)CHANNEL
What substance expand to fill the entire volume of its container?
A gas can expand to fill the entire volume of its container because the particles are not confined and can move freely. When a gas is placed in a container, it will fill the entire space available to it.
What is A-B squared?
(a-b)^2 doesn't have a numeric value since there are no numbers associated with it, but you can definitely expand it, as it represents a formula, instead of an actual numeric expression.(a-b)(a-b)= a^2-ab-ab+b^2= a^2-2ab+b^2 (which is actually the rule for expanding!)
