How do you factor of a4 plus b4-7a2b2?
Usually simple substitutions enable such expressions to be seen as quadratic expressions. The substitutions x = a2 and y = b2 give a4 + b4 - 7a2b2 = x2 - 7xy + y2 which does not have any rational factors. Consequently, the quartic in a and b does not have rational factors.
Which of the following is an exaple of a bionominal 2y 2X y 2xy?
All of these are monomials. The binomials are algebraic expressions consisting of two terms. A term is a constant, a variable, or a combination of constants and variables. 2y, 2x, y, and 2xy consisting of only one term, so they are monomials. Examples of binomials: 2 + 5, 2x + 3, 3x + 7y, 2xyz + 7xy,...
What are all the factors of 7xyz?
The factors of 7xyz would include 1, 7, x, y, z, and any combination of these factors. Factors are numbers or variables that can be multiplied together to give the original number or expression. In this case, the factors of 7xyz would be all the numbers and variables that divide evenly into 7xyz without leaving a remainder.
What is x in 7 plus 4x equals 34 plus x?
7 + 4x = 34 + x Don't expect answers for homework, but I'll do this one. The rule for ANY math equation is to apply the same operation to both sides including using the same numbers. (operations are +,-,/,*, etc). And you can combine numbers with the same type of variable or lack of (e.g. 2x + 3x = 5x or 2 + 2 = 4 or 5yx + 7xy = 13xy) (7 + 4x) - 7 = (34 + x) -7 // subtract 7 on both sides 4x = 26 + x (4x) - x = (27 + x ) - x // subtract x on both sides 3x = 27 (3x)/3 = 27/3 // divide by 3 on both sides x = 9 check the answer 7 + 4*(9) = 34 + 9 7 + 36 = 43 43 = 43; so correct Writing this is a long form, but do this when you are first learning, then simplify your writing as you figure tricks or can do it in you head.

How do you factor the expression x cubed y cubed minus 343?
(xy - 7)(x^2y^2 + 7xy + 49)
What is the greatest common factor of 14x5y4 and 7xy3?
The GCF is 7xy^3
When 63x3y 105x2y is divided by -7xy the quotient?
-9x^2 - 15x

5x(7xy + 6x + 8)
What is An equation with a degree of 2?
A quadratic. For example, x^2 + 3x - 7xy - 12y - 25 = 0
Factor by factoring out the greatest common factor -7x5y3-42x3y2 plus 35xy?
-7xy(x4y2 + 6x2y - 5)
Greatest common factor of 35x power 2 and 7xy power 2 and 21x power 2y power 2?
gcf(35x², 7xy², 21x²y²) = 7x 35x² = 5 times 7 times x² 7xy² = 7 times x times y² 21x²y² = 3 times 7 times x² times y² hcf = 7 times x = 7x (I've written the multiplication as times instead of using the × symbol to avoid confusion with the unknown x.)
What does magic one mean in math?
It means "1" is the magic number, like if you were to have a math problem that looked like this:7xy-xy+3xIt means use the "magic one" to combine 7xy and 1xyIf that doesn't make sense you should probably state the question like this:What does the "Magic 1" mean in math?
How would the sum of cubes formula be used to factor x3y3 343?
(xy + 7)(x^2y^2 - 7xy + 49)
How do you simplify x3y2 plus 7x2y3 plus 7xy-2 plus x2y3 plus 8x3y2-3xy-7?
x3y2 + 7x2y3 + 7xy - 2 + x2y3 + 8x3y2 - 3xy - 7 =9x3y2 + 8x2y3 + 4xy - 9 =xy ( 9x2y + 8xy2 + 4) - 9 =xy ( xy(9x + 8y) + 4) - 9 .This is still messy, but it's simpler than the octonomial in the question,and we can't see any more that can be done with it.
