What is the algebraic expression for the cube of a plus b?
It could be a^3 + b or (a + b)^3, depending on the context.
Is absolute value of a and b is equal to the absolute value of a plus the absolute value of b?
Only when a and b have the same sign (or when a or b equals 0). Here are some examples: |2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE |(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE |3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE
What is a rational algebraic expression?
A rational number is any number that can be written in the form a/b, where a and b are integers and b ≠0. it is necessary to exclude 0 because the fraction represents a ÷ b, and division by zero is undefined.A rational expression is an expression that can be written in the form P/Q where P and Q are polynomials and the value of Q is not zero.Some examples of rational expressions:-5/3; (x^2 + 1)/2; 7/(y -1); (ab)/c; [(a^2)(b]/c^2; (z^2 + 3z + 2)/ (z + 1) ect.Like a rational number, a rational expression represents a division, and so the denominator cannot be 0. A rational expression is undefined for any value of the variable that makes the denominator equal to 0. So we say that the domain for a rational expression is all real numbers except those that make the denominator equal to 0.Examples:1) x/2Since the denominator is 2, which is a constant, the expression is defined for all real number values of x.2) 2/xSince the denominator x is a variable, the expression is undefined when x = 03) 2/(x - 1)x - 1 ≠0x ≠1The domain is {x| x ≠1}. Or you can say:The expression is undefined when x = 1.4) 2/(x^2 + 1)Since the denominator never will equal to 0, the domain is all real number values of x.

What is a quadratic expression?
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
A plus b?
The value of a + b depends on the values of the individual variables.The expression a + b cannot be simplified.
How can you write the expression a plus b plus a-b in equivalent form not involving absolute value.?
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
If the expression 5x 3 2 is written in the form ax b what is the value of a plus b?
The values of a and b would be assumed to be 3 and 10 or 2 and 15.
What is 2a plus b?
2a+b=2a+b. Without a value for a and b, the expression has no value.
How do you solve this equation a plus 7 equals 10 plus b?
you can't get a value for either a or b from just the information you have given - you can only get an expression for what a is in terms of b and vice versa; a=3+b b=a-3
Write an algebra expression for -8 is less than b and 0 is greater than b?
-8<b<0
The product of a and b divided by an expression that is 3 times their difference?
The answer to the product of a and b divided by an expression that is 3 times their difference is 3ab(a+b).
How do you determine whether an expression is rational algebraic expression or not?
If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠0, then the expression is a rational algebraic expression.
If the value of b is 7 then what is the value of expression -3b-25?
replace b with 7 so you must first multiply -3 by 7 which gives you -21. Subtract 25 more and you get -46, which is the answer.
What is principal of Duality?
According to principle of duality"Dual of one expression is obtained by replacing AND (.)with OR(+) and OR with AND together with replacement of 1 with 0 and 0 with 1. For example: consider the expression A+B=0. The dual of this expression is obtained by replacind + with . and 0 by 1. ie A.B=1 is dual of A+B=0
Can a term in an algebraic expression be zero?
Yes they can, for example quadratic expressions are often written in the form, ax^2+bx+c, where x is a variable, and a,b,c are constants. If you have an expression such as 5x^2 - 3, then clearly a=5, c=-3 and b=0
What is the algebraic expression for the cube of a plus b?
It could be a^3 + b or (a + b)^3, depending on the context.
